When will the green plum mature?

Question 1: What month is the childhood season? There was a poem saying, "It rains at home in Huangmei season, and frogs are everywhere in the grass pond." Rainy days, this poetic name is worthy of the name in this season. In this season, it means that plums are ripe for picking. And this time is just right, the late spring season is around May, so the plum season is when the plums are not mature, almost in the middle and late April.

Question 2: When is the best time to plant green plums? Prunus mume is a Dipterocarpaceae tree with a height of 30m, a DBH1.2m and a blue-gray bark. Young branches and leaves are densely stellate hairy. Thymus with small white flowers. Fruit subglobose, with 2 long wings and 3 short wings, enlarged by sepals.

China is only distributed in Hainan. It was born on the beach at an altitude of 3-4 meters, all the way to the barren hillside at an altitude of 900 meters.

Common in 200-500 meters above sea level. Thailand, Taiwan Province Province, Malaysia, Indonesia and the Philippines are also distributed. Endangered species under national third-class protection.

Plum blossom is a deciduous fruit tree of Rosaceae, which is native to China. In order to obtain high yield and high quality of plum blossom, the following conditions are needed: suitable climatic conditions and cultivation environment, selection of excellent varieties, rational allocation of pollination trees and bees at flowering stage, and implementation of scientific cultivation techniques.

1, and select the appropriate culture environment.

Plum blossoms are suitable for warm climate and cold tolerance. At the flowering stage of -8 ~-9℃, the cold resistance of young fruits weakened and they were frozen at -3 ~-5℃. The planting place should be a place with good lighting conditions, no pollution around and sufficient water. The soil layer in the garden is deep, fertile, moist and well drained. Generally, the green plum base should be built in a relatively flat mountain nest or halfway up the mountain.

2, planting high-yield and high-quality varieties, reasonable collocation, and releasing bees during flowering.

At present, the main cultivars of plum blossom are Mei Tao, Plum, Bai Mei, Soft Branch and Big Plum. In addition to these varieties, excellent varieties with the same or similar flowering periods should be used as pollination trees in a certain proportion, such as 80%-90% plum as the main planting, 10%-20% peach plum, 70% peach plum with 30% Ber Ber, or 60% plum with 40% peach plum and other pollination combinations. If the existing pollinated varieties in the original plantation are insufficient, the high grafting method should be adopted to replace a certain proportion of pollinated varieties. In addition to matching pollinated varieties with the same or similar flowering period, bees should also be released at flowering period. Generally, 1-2 swarms of bees should be released per mu of orchard.

3. Reasonable planting of 40-60 plants per mu in thin mountain land and 30-40 plants per mu in flat and fertile land. Orchards that are planted too densely, cover each other and affect photosynthesis should be interplanted and pruned in time.

4. Strengthen fertilizer and water management.

Fertilization of young trees is based on the principle of thin fertilizer and quick-acting fertilizer. Results The tree was fertilized three times a year, the first time after fruit picking, the second time before flowering and the third time in the small fruit period after flowering. Before flowering, high-quality organic fertilizer should be applied, mainly human and animal manure, cake fertilizer or farm manure, which accounts for 2/3 of the annual fertilization. Foliar fertilizers such as potassium dihydrogen phosphate were applied to the roots in bud stage and small fruit stage, and appropriate lime was applied to supplement calcium to neutralize the soil pH value. In case of dry weather during flowering and young fruit period, irrigation should be done in time; In case of dense fog and frost, clear water should be sprayed to wash the fog and frost in the morning to prevent the stigma of female flowers from drying, which is beneficial to improve the fruit setting rate. After picking every year, cover the fruit with a layer of 3-6 cm thick new soil to protect the root system and promote the growth of new roots.

5. Dressing and shaping

Plum blossom is a light-loving plant. Timely pruning and plastic surgery is helpful to form a natural happy crown and promote ventilation and light transmission of the crown. Plastic surgery begins with young trees, and the trunk is about 60 cm high for pruning. There are three main branches in different directions on the trunk, and the bifurcation angle is 40-50 degrees. Pick the main branches at 50-60 cm to promote their branching, leaving 2-3 branches for each main branch to basically form the crown skeleton, and then let them continue to branch into a natural happy crown.

As a result, trees should be pruned in time. The first pruning should be carried out after spring shoot germination or fruit picking in small fruit period, and the second pruning should be carried out before flowering, so as to promote ventilation and light transmission of the crown, concentrate nutrients and reduce the harm of pests and diseases.

6. Strengthen pest control.

(1) pests

Focus on the prevention and control of aphid new shoot pests in small fruit stage and spring shoot germination stage, which can be sprayed 500 times, or 1500-2000 times, or 3000 times, or 1000 times. In summer, all kinds of leaf-eating insects are mainly controlled, and pyrethroids and other pesticides can be used for control.

(2) disease

Spray 1 time in bud stage and small fruit stage respectively. 1%―0? 2% borax to control fruit gummosis. Timely control of scab in new shoot stage and fruit expansion stage. Commonly used pesticides are 500 times of copper chloride, 600-800 times of copper chloride, 800 times of chlorfenapyr and 800 times of thiophanate.

Pest control should be combined with clearing the garden in winter, painting the trunk and spraying turpentine mixture or sulfur mixture to wash the branches, so as to eliminate the source of overwintering pests and diseases.

Question 3: When will the green plum be listed? Prunus mume is a tree of Dipterocarpaceae, with a height of 30m, DBH 1.2m and a bluish gray bark. Young branches and leaves are densely stellate hairy. Thymus with small white flowers. Fruit subglobose, with 2 long wings and 3 short wings, enlarged by sepals. Most of them are distributed in Zhao 'an, Puning, Hainan, Taiwan Province and southeast Anhui. Born in the barren slope from the beach at an altitude of 3-4m to 900m, it is mostly found in the area at an altitude of 200-500m. Pruning has a history of about 700 years.

Picking green plums from late May to early June every year.

Question 4: In what season are there plums? Primitive Perianth of Reticulata Subclass Garcinia Subclass Garcinia Subclass Trollida Subclass Dipterocarpaceae Prunus mume, Reticulata Subclass, Angiosperms.

Question 5: Plum fruit ripens in a few months. Hello, our family grows plums, which ripen from April to May every year!

Question 6: When do plums usually ripen? From March to April, Tomb-Sweeping Day

Question 7: When are fresh plums available? If there is kimchi in Dongguan, you can serve it first. Where are the plums cooked now ... Hehe.

Question 8: Where is the birthplace of plums? When does it usually expire? Besides fresh plums, are there any homemade plums that have been preserved for a long time? Zhaoan, the hometown of plums in China, has unique soil, water quality and climate conditions suitable for the production of plums. People have been planting plums for a long time since the Southern Song Dynasty. Over the years, fruit farmers have rich experience in planting and breeding. After years of evolution and development, Zhao 'anmei has formed two unique varieties, namely "Bai Mei" and "Qingzhumei", which are collectively called "Zhao 'anmei". It is famous at home and abroad for its large fruit, thin skin, thick meat, small stone and moderate acidity. Its quality is comparable to that of Nangao plum in Japan, and the finished plum is rated as the first-class product. At present, Zhaoan has become the largest plum planting base in China. The planting area of plums in the county is 1.24 million mu, and the output is 60,000 tons. 70% of the planting area and output are concentrated in the neighboring towns of Hongxing and Taiping. The processed products of plum in Xinxing County are mainly preserved plum and salted plum. At present, there are more than 60 enterprises 160 and a wide range of family workshops 1000 in the county. "Xinxing Huamei" has a history of nearly a hundred years, and its products are well-known in all directions. After years of development, preserved fruit products with sour, sweet, sweet and salty tastes have been formed, and the products have also developed from simple processing to deep processing. Product sales network all over the country, but also exported to Japan, Australia, Southeast Asia, Europe and the United States and other countries and regions.

Question 9: Can ripe plums be eaten when they turn yellow? Yes, cooking and efficacy: making dried fruits.

Production materials of green plums: main ingredients: green plums. Teach you how to make green plums and how to make them delicious. 1. Raw materials require green apricots with thick meat, no diseases and scars, and the maturity of nuclear hardness is about 50-60%.

2. Pickling: in a vat (or cement pool), add salted apricots layer by layer, 65,438+000 kg of salted apricots, 65,438+08 ~ 20 kg of salted apricots, and add clear water until the apricots are not exposed, and marinate for 7 ~ 65,438+00 days.

3. Half pressing: Take the pickled apricots out of the jar, and press the apricots in half with boards connected at two ends. Remove the apricot kernel and apricot stalk. Make neat apricot blanks.

4. Desalination: Put the apricot blank into a jar, soak it in clear water for about 2 hours, and change the water for 3-4 times to make the apricot blank basically salty. After the last water change, 60 g of sodium sulfite and 100 kg of alum were added to 1 kg of apricots to make the apricots more transparent, bright and hard.

5. Sugar stain: put a layer of apricot and a layer of sugar in the jar, 100 kg of apricot and 65-70 kg of sugar, and the sugar stain time is generally 24 hours, so that the apricot blank can fully absorb sugar.

6. Sugar boiling: The texture of green apricots is relatively solid, and the method of sugar boiling for many times is generally adopted. For example, cook for 4 times: put the sugar-stained apricot blank and soup in a pot, boil it, and then put the soup in a jar for 24 hours. Pay attention to sliding the cylinder every time to prevent the apricot blank from changing color. If it is boiled three times and four times, take out the sugar solution and spread it on the steamer. To enhance the bright cyan. When sugar is boiled for the first time, 100 kg apricot embryo can be added with 10 g lemon yellow and indigo respectively, and 300 g alum to promote dyeing.

7. Drying: You can dry in the sun on sunny days. Because of its high sugar content, it can especially prevent pollution from flies and other insects. In order to dry quickly, the steamer was put into the curing barn, and the temperature was controlled at 50 ~ 60℃. Turn it once every hour to ensure uniform heating, dry it once and bake it for about 8 ~ 9 hours. Make the water content reach 16 ~ 18%.
