High-yielding planting techniques of "Changshengguo" Peanut

Peanuts, also known as peanuts and muddy beans, are popular nuts and are one of the raw materials for oil, soap, cosmetics and non-staple food with rich nutritional value. So, what are the high-yield planting techniques for peanuts? Let's get to know it together.

I. pre-broadcast preparation

1. Soil selection

Peanuts are generally planted in sandy soil with loose soil, deep soil layer, neutral acid, good drainage and fertility characteristics, and the peanuts grown in this soil have good high yield and quality.

2. Rotation land

Keep in mind that the yield of peanuts will be reduced when they encounter continuous cropping. According to the relevant experiments, the yield of pods will be reduced by more than 15% after one year of continuous cropping, and the yield will be reduced by more than 30% after more than two years. Therefore, when you encounter continuous cropping land, it should be remembered as soil disinfection to improve soil fertility.

3. Land preparation

Choose large peanut seeds, large seeds with high fat content, need a lot of water and oxygen when germination and emergence, and the requirements of soil preparation before sowing are loose soil, fine crushing, non-hardening, moderate water content and good drainage.

Second, sowing preparation

1. Drying the seeds

Peanuts are sunburned continuously for 2-3 days about a week before sowing, in order to improve seed vigor, seedling emergence and germination rate. In addition, after high temperature disinfection by sunlight, the pathogens on the pods will be killed, reducing the incidence of peanut in the field and saving effort for later sowing.

2. Select seeds

In fruit selection, shelling will be carried out, and the different fruits, buds, insects and rotten fruits that do not match the characteristics of the variety should be removed at any time, and the fully developed peanut kernels should be selected, otherwise the high yield can not be achieved.

3. Peeling peanuts

The time of peeling should not be too early, because after peeling, peanut seeds are easy to absorb water, enhance respiration, accelerate enzyme activity, promote material transformation, and consume a lot of water, which will reduce the germination ability. therefore, the closer the peanut peeling time to the sowing time, the better.

Third, sowing method

The main results are as follows: 1. Peanut seed germination requires that the temperature must be suitable, preferably at 12-15 ℃, so sowing should be carried out only when the soil temperature is 5 cm and the ground temperature is constant above 12 ℃. Early sowing under permissible conditions can relatively prolong the growth period of peanut, early flowering, many lateral branches and well-developed roots, and create conditions for high yield.

2. The method of sowing

According to the planting mode, we can be divided into open-field sowing and film-covered sowing, the sowing density is about 20-25cm, single-grain sowing; sowing depth is about 5 cm, we should grasp the secret of dry or not deep, wet not shallow.

IV. Fertilization technology

With autumn soil preparation and ridging, application of rotten ring manure, Kang hole soil, retting green manure, etc., applying 15000-30000 kg per hectare, ridge cultivation, ditching, sparse application, border spreading, ridge cultivation can also sparsely apply agricultural fertilizer before sowing in the same year. During sowing, 150-225kg/ hectares of diammonium phosphate and 75~120kg/ hectares of potassium sulfate are applied as seed fertilizer, and lime is applied along with the base fertilizer, such as pH value (pH) 6.06.5. Lime 450kg/ ha, pH 5.5-6.0m, lime 675kg/ ha.
