Excuse me, can I plant peanuts now? Peanut planting steps are attached.
1. Can I plant flowers now?
1. Can we plant flowers now?
At present, it is May, and peanuts can generally be planted. Generally, the suitable time for planting peanuts is from mid-late April to early May, that is, around Grain Rain. If the plastic film mulching method is adopted, it can be planted in the middle and late March in advance, but the climate is different in different places, and the specific sowing date needs to be flexibly adjusted according to the actual situation.
2. Conditions for planting peanuts
(1) temperature
Peanut 1 is a thermophilic crop and is very sensitive to temperature. Generally, the average temperature of the whole growth period should be higher than 265,438 0℃, and the total active accumulated temperature should be higher than 3,200℃ ... The average daily temperature of seedling emergence should be higher than 65,438 05℃, and the active accumulated temperature should be 200-230℃ ....
2. The average daily temperature at flowering and fruiting stage should be greater than 23℃, and the active accumulated temperature should be 600-650℃ ... The average daily temperature at pod setting stage should be greater than 25℃, the active accumulated temperature should be 1200- 1300℃, the average daily temperature at full fruit maturity stage should be greater than 18℃, and the active accumulated temperature should be 60.
(2) Moisture
Peanut is drought tolerant, but it needs to provide suitable water to promote high yield. Generally, it takes about 94 cubic meters of water to produce 100kg peanut pods, and the water consumption in peanut seedling stage, seedling stage, flowering and needle setting stage, pod setting stage and fruit maturity stage generally accounts for 3.4%, 1 1.2%, 2 1.8% and 50% of the total water consumption in the whole growth period respectively.
(3) Lighting
The whole growth period of peanut 1 sunshine hours is generally above 1250 hours, in which peanut seedling needs 205 hours, with an average of 13.67 hours per day. The seedling stage needs 2 14 hours, with an average of 8.56 hours per day.
When peanuts are in flowering, it usually takes 308 hours, with an average of 8.32 hours a day. It takes 3 18 hours for pod setting, with an average of 6.36 hours per day, while it takes 275 hours for fruit to fully mature, with an average of 7.85 hours per day.
(4) Soil
Peanut is suitable for planting in loam or sandy loam with deep soil layer, fertile soil and good drainage (PH 6.3-6.8).
Second, the steps of planting peanuts
1, seed selection and germination acceleration
First, select full and shiny peanut seeds, then peel them, soak them in clear water 1 night, then take out the seeds, put them in plastic bags and seal them to accelerate germination, and sow them after the seeds sprout.
2. Land selection and preparation
Selecting deep soil for deep ploughing, the suitable depth is 25-30cm, which can enhance the drought resistance and waterlogging tolerance of soil and promote peanut growth.
3, sowing time and method
(1) Usually in spring, when the ground temperature of 5cm is stable at 12℃, the seeds can be sown in April-May.
(2) First, put peanut seeds in the pit and apply some fertilizer in the pit. Generally, 0.2 kg of fertilizer can be put in each pit. Note: chemical fertilizer can't be used because the seeds have sprouted. If chemical fertilizer is applied, it will easily lead to root rot. The planting density is generally 50cm between ridges, 13- 17cm between holes, and 2 seeds are sown in each hole.
(3) After sowing, the covering soil thickness is about 3cm.
4. Tian Tuan management
(1) Generally speaking, it takes about 15 days for peanuts to grow on the ground from sowing to rooting and germination. During this period, weeding, loosening soil and fertilization should be done well, and urea can generally be applied.
(2) Generally, the ratio of nitrogen fertilizer 1 1 kg, phosphorus fertilizer 6 kg and potassium fertilizer 8 kg can be applied to peanuts at flowering stage, because peanuts need a lot of nutrients to grow normally at flowering stage.
(3) Peanut is drought-tolerant, and generally does not need watering in normal years, but it needs watering in extremely dry weather, especially in flowering period. However, in the mature period when the requirement for soil water content is not high, if the soil water content exceeds 2/5 of the normal soil water content, it is necessary to drain water to prevent peanut rot.
5, prevention of pests and diseases
(1) brown spot disease
Characteristics of 1: the lesion is dark brown in color and prototype in shape, with yellow halo on the outer edge, and gray mold will appear in the later stage of the disease.
2 control method: 70% thiophanate methyl wettable powder or 50% dolorine wettable powder 1500 times solution can be used for control.
(2) Rusting
Characteristics of 1: There will be small blister spots on the leaves, and the color is yellow. When the epidermis cracks, it will release rust-colored powder. When the disease is serious, the leaves will dry up, yellow and fall off.
2 Prevention and treatment methods: 75% chlorothalonil 600 times solution or 25% triadimefon 500 times solution can be sprayed all over the field at the initial stage of the disease.
(3) Soil tigers and grubs
Characteristics of 1: The cutworms and grubs usually hatch in early to mid-July, endangering needles and young fruits, thus causing peanut seedling shortage and ridge breakage, and affecting peanut yield.
2 prevention and control methods: the soil can be treated with chemicals. Generally, 200-250g of 50% phoxim emulsifiable concentrate is used per mu, and 25-30kg of fine soil is sprayed with 10 times of water, then mixed evenly to make toxic soil, applied along the ridge, and then shallow ploughed.
(4) Aphids
Characteristics of 1: Aphids not only suck peanut juice, resulting in short plants and curly leaves, but also are the main vectors for spreading viruses, seriously affecting peanut fruits.
2 Control method: 1.5% dimethoate powder or 0.5 kg of 2.5% trichlorfon powder can be mixed with 15 kg of fine dry soil (sand) and sprinkled on the base of peanut mound in the morning and evening when the leaves are closed.
