It’s another year of peanut planting. At this time of year, we are worried about many peanut problems. Peanut early sowing is beneficial to prolong the vegetative growth period and increase nutrient accumulation, but it also faces many adverse factors. So how to grasp the best sowing time of peanuts and how to plant peanuts? Today we’ll talk about it in detail.
1、 Planting method of peanut:
1. Sowing method. The sowing methods of peanut are open field sowing and film mulching sowing according to the cultivation methods. According to the operation mode, it is divided into manual on-demand sowing and mechanical sowing.
2. Seeding density. We should master the principle of reasonable close planting. The planting density of peanut depends on plant height, seed setting range and leaf area. The suitable planting density of peanut depends on climate characteristics, soil fertility, selected varieties and cultivation conditions. Generally, the plant row spacing is 5 × 8-inch, double kernel planting, sowing more than 23000 basic seedlings per mu, and harvesting about 20000 seedlings. Kaixing shall try to use peanut specifications for farming or peanut hole fixing device, and plant six rows per border.
3. Sowing depth. Generally, the sowing of peanuts should be about 5cm. We should master the principles of “no deep planting in dry and no shallow planting in wet” and that the soil should be shallow and the sandy land or sandy land should be deep. The depth of open field cultivation shall not exceed 7 cm, and the shallowest shall not be less than 3 cm.
4. Post broadcast repression. Suppression after sowing is a successful experience of peanut drought resistance sowing to ensure the whole seedling. After suppression, it can not only reduce soil water evaporation, but also make the seeds in close contact with the soil, promote the rise of water in the lower layer of the soil, prevent the seeds from drying, and facilitate the germination and emergence of seeds.
2、 The best planting time of peanut:
Generally speaking, peanut is a thermophilic crop, so the temperature must be appropriate, and the most suitable stability for peanut sowing is about 12 ℃. At the same time, the most suitable temperature for its flowering is 23-28 ℃, and the lowest temperature is 19 ℃.
General peanut sowing period: when peanut is sown, the soil temperature 10 cm deep lasts for 5 days and can be sown when it is stable above 15 degrees. Remember not to sow when the temperature is lower than 11 degrees to prevent the appearance of rotten seeds and dead seedlings. Even if peanut can be unearthed, peanut seedlings are not robust and affect the yield. Generally, the best planting time of peanut is from mid and late April to early May, that is, before and after Gu Yu, which is the best time for peanut planting. Plastic film mulching can be sown in advance to the middle and late March. However, the climate conditions are different everywhere, so when planting peanuts, we should decide according to the actual situation, but we must ensure that we don’t sow when the temperature is too low!
2-3 days before sowing, the peanuts with shells shall be dried, peeled after drying, mixed with 50% imidacloprid suspension seed coating agent + manshijin suspension seed coating agent, and sowed after drying. 2-3 seeds shall be sown in each hole, and the sowing depth shall be 1.5 inches. The soil with sticky soil and good moisture content can be shallower, and the soil with sandy soil and poor moisture content can be deeper. It is suggested that spring peanut planting areas should be covered with plastic film, which can be sown appropriately early to improve peanut yield.
Summer peanut planting areas can choose interplanting and sowing in advance to improve yield.
Mastering the planting method and the best planting time of peanut can not only prevent the problems caused by peanut sowing, but also effectively increase the yield of peanut. We should also remind you to deal with the changeable weather in the near future.
