When will the peanuts be harvested in spring?

Question 1: Harvest time of spring peanuts The best harvest time of spring peanuts is from the end of August to the beginning of 10, which is also the harvest season of plastic film peanuts and open-field peanuts. The suitable harvest time of peanuts should generally be determined according to the appearance standards of plant appearance and pod maturity. From the outside of the plant, the upper leaves turn yellow, the middle and lower leaves turn yellow and gradually fall off, and the stems are yellow-green; The appearance standard of pod maturity is: the shell is blue and hard, the vein texture is deep and clear, the sponge in the shell is shiny dark brown, the seeds are full and full, and the seed coat is bright.

Spring peanuts are harvested in the northern hemisphere from July to September every year; In the southern hemisphere, it is 1 to harvest in March. After September, the northern part of China is the best place to harvest peanuts. Sowing in April and harvesting in August-September are common in Jianghuai area.

Question 2: When will the peanuts be harvested? It is not good to harvest peanuts too early or too late. Early harvest, pod shrinkage, yield and oil content decreased; If the harvest is too late, not only the cones will be easily broken, which will bring difficulties to the harvest, but also the quality of pods will be reduced when the temperature drops gradually. In particular, some peanut varieties with short dormancy period will germinate in large quantities, which will affect the yield and quality. Therefore, to achieve high yield, it is necessary to harvest in time. Under normal circumstances, when the aboveground stems and leaves of peanuts turn from green to yellow, the lower leaves fall off, the underground roots are aging, the pod skin is bright in color, the reticulation is clear, and the skin has dark brown spots, accounting for about 70%, and the color of the seed coat has met the color of the original variety, it should be harvested in time.

Peanut and other crops in different areas of China form a planting system of one crop a year, three crops a year, two crops a year or three crops a year, which can be divided into spring peanuts, wheat peanuts, summer peanuts and autumn peanuts, and winter peanuts can also be planted in some areas of Guangdong. In recent years, some peanuts have been planted in rice fields, forming a peanut-rice or rice-peanut rotation system. In some places, the growing season is longer, the rice variety is suitable, and it can also be rotated with double cropping rice. The autumn peanut pods planted in Guangdong and Fujian are reserved for the second spring sowing, which can improve the emergence rate and ensure the whole seedling in Miao Zhuang, commonly known as "turning over the autumn seeds" or "spring sowing" Loose sandy soil, sandy gravel soil or sandy loam soil are needed for underground pod setting, which is beneficial to the penetration of fruit needles, the development and harvest of pods. Deep ploughing and deep ploughing are beneficial to the growth and development of peanuts.

Peanut has certain adaptability to slightly acidic soil and is a pioneer crop in developing red loam. However, high soil acidity requires the application of calcareous fertilizers such as lime to neutralize short-day crops, but it is not sensitive to photoperiod. Only when the daily average temperature is stable above 65438 02℃ can sowing be carried out; The main growth period requires a temperature of 20 ~ 28℃. In autumn, when the temperature drops to about 1 1℃, the pod stops developing. The average accumulated temperature of peanut in China is around 3500℃. The growth period is 100 ~ 150 days, and individual late-maturing varieties can reach 180 days. Generally, the seed dormancy period of early-maturing varieties is short, the dormancy period of late-maturing varieties is long, and Longsheng varieties are the strongest. The dormancy of peanut seeds is not only affected by the seed coat, but also related to some hormones in the embryo. Using chemicals such as ethephon and kinetin, seeds can be dried and germinated at a suitable temperature, which can relieve dormancy.

Question 3: When will spring peanuts be harvested in Nanyang, Henan? Generally, peanuts can be harvested in 120 days after sowing, that is, peanuts can be harvested in about 4 months.

Question 4: When will the peanuts ripen? Peanuts ripen around July, and in the summer of early autumn, when wheat ripens, peanuts are almost ripe! That's the normal season. Now many peanuts are planted in greenhouses, some early and some late! Natural and seasonal are more delicious! Especially the ones planted in their own fields are more fragrant than those bought in the supermarket!

Question 5: When will spring peanuts be planted? From the middle and late February to the end of March in the lunar calendar, the solar calendar can generally be planted from the end of March to the end of April. After this time, it is generally not very rewarding. I grow melons and beans and sell agricultural materials around Qingming Festival, so there are many crops that can be planted at this time, such as peas and broad beans. Other melons and beans should be planted in September of the lunar calendar.

Supplement: end of April and beginning of May.

Methods: The normal growth cycle of peanut is 100 ~ 150 days.

Autumn peanuts. Sowing in late July, the furrow width is 85cm, the furrow depth is more than 25cm, the furrow surface is 20cm, and the hole spacing is about 18cm. Before sowing, carefully select the seeds, and the depth is the same when sowing to ensure the whole seedling. Autumn peanut has short seedling stage and early flowering. Generally, it blooms about 15-20 days after emergence, and its growth potential is weak. Therefore, when planting, more base fertilizer should be applied, with high-quality base fertilizer per mu 1000 kg, phosphate fertilizer 25 kg and plant ash 50 kg. When there are 3-4 real leaves on the main stem, about 5 kg of urea and 2.5 kg of potassium fertilizer should be applied in time to promote the vigorous growth of seedlings. At the same time, we should do a good job in intertillage weeding, moisture preservation and drought resistance, pest control and timely harvest.

It depends on the variety of peanuts, usually from August to 10.

The complete maturity of peanut fruit can also be called late growth stage, which refers to a period of time from half of the plants to most of the pods, that is, mature harvest. Medium-mature varieties last for about 35 ~ 45 days, extremely early-maturing and early-maturing varieties are shorter, and late-maturing varieties are longer. Summer direct sowing peanuts is equivalent to or slightly longer than spring sowing. In Shandong province, spring peanuts are from early August to mid-September, and summer direct sowing peanuts are from the end of August to the beginning of 10. The growth and development characteristics of peanut fruit at maturity are that the growth of stems, leaves and other nutrients reaches a peak and begins to decline, and the middle and lower leaves turn yellow and fall off; The absorption capacity of roots is weakened, and the nitrogen fixation and supply capacity of nodules are reduced; The center of growth shifted to the propagator, and a large amount of nutrients accumulated in the stems and leaves moved into pods and quickly enriched; The number of effective needles and pods rarely or no longer increased, but the number of full fruits and the weight of single fruit increased rapidly. The increased fruit weight in this period can generally account for more than 60% of the total weight, which is an important period to form economic output. The main task of field management is to slow down the aging and yellowing speed of leaves, delay the defoliation time, maintain a large green leaf area and maintain a long functional time; Enhance photosynthetic intensity, improve photosynthetic efficiency and increase nutrient accumulation; Promote the nutrients in the stems and leaves to move into the pods, improve the moving speed, accelerate the pod enrichment, and form economic output as soon as possible; Control the harm of main pests and diseases and reduce production losses.

Question 6: Spring sowing time and sowing date of spring peanuts.

Due to the different climatic conditions in different regions, the cultivation techniques of spring peanuts are also different. Under normal circumstances, multi-grain varieties are mainly planted in cold and frost-free areas in the north; Most common varieties are planted in peanut areas in northern China. The sowing time of spring peanuts is as follows:

The suitable sowing date for spring and autumn peanut areas in South China is from mid-February to mid-March, and the suitable sowing date for spring and summer peanut intercropping areas in the Yangtze River Basin is from late March to late April. The suitable sowing period in the northern peanut region and peanut producing area is mostly from late April to early May. Germination temperature of peanut: Beaded type and multi-grain type can germinate above 12℃, while common type and dragon type can germinate above 15℃, and the sowing date is a little late.

Sowing spring peanuts in time can improve the utilization rate of land and light energy, make plants grow short and strong, with dense internodes, many branches, good root growth, more dry matter accumulation, more flowers and fruits, and high fruit fullness rate, which is easy to meet the requirements of high yield and high quality. Premature sowing, because of the low temperature, seeds can not germinate normally, and the emergence is slow, which increases the chance of soil diseases and insect pests, and the emergence rate is low, and the seedling growth is poor, which affects the differentiation and development of flower buds; However, sowing is too late, and the southern producing area is in a high temperature and rainy environment, so peanuts are easy to grow and lodging, and there are few pods; Peanuts in central and northern China, especially common peanuts, often suffer from autumn drought and low temperature during pod setting and maturity, which affects pod development and nutrient accumulation, resulting in low full fruit rate, kernel rate and oil content, and reduces yield and quality. When interplanting or sowing peanuts in summer, early-maturing varieties should be selected as the previous crops to avoid the yield reduction caused by late sowing of peanuts.

Question 7: When will the peanuts ripen? Medium-mature varieties last about 35 ~ 45 days, extremely early-maturing and early-maturing varieties are shorter, and late-maturing varieties are longer. The direct seeding time of peanut in summer is equal to or slightly longer than that in spring. In Shandong province, spring peanuts are from early August to mid-September, and summer direct sowing peanuts are from the end of August to the beginning of 10.

Question 8: Where are the spring peanuts harvested in 2065438+06? Changle Town, Hepu County, Beihai City, Guangxi Province

Question 9: In which season were peanuts harvested?

Peanut and other crops in different areas of China form a planting system of one crop a year, three crops a year, two crops a year or three crops a year, which can be divided into spring peanuts, wheat peanuts, summer peanuts and autumn peanuts, and winter peanuts can also be planted in some areas of Guangdong.

In recent years, some peanuts have been planted in rice fields, forming a peanut-rice or rice-peanut rotation system. In some places, the growing season is longer, the rice variety is suitable, and it can also be rotated with double cropping rice.

The autumn peanut pods planted in Guangdong and Fujian are reserved for the second spring sowing, which can improve the emergence rate and ensure the whole seedling in Miao Zhuang, commonly known as "turning over the autumn seeds" or "spring sowing" Loose sandy soil, sandy gravel soil or sandy loam soil are needed for underground pod setting, which is beneficial to the penetration of fruit needles, the development and harvest of pods. Deep ploughing and deep ploughing are beneficial to the growth and development of peanuts.
