When is the best time to fertilize peanuts? when is the best time for peanuts to control their prosperity?

Nowadays, people have very high requirements in terms of diet. They should choose healthy foods as well as foods with very high nutrition. Today, a kind of food to be introduced to you is called peanuts. Peanuts are also a kind of food that everyone can often eat in their daily life. Many friends in the countryside also like to plant some peanuts at home, so when is the best time to fertilize peanuts?

When is the best time to fertilize peanuts

Before sowing, select yellow brown earth plots with deep living soil layer, fertile soil and convenient drainage and irrigation. Deep ploughing shall be carried out after autumn harvest, and shallow ploughing and multiple harrowing shall be carried out after spring, i.e. harrowing deeply and thoroughly, harrowing solid and flat, and the ground shall be flat without debris, dark Dai and sundries. Apply 2500 -3000kg of high-quality organic fertilizer, 20 -25kg of diammonium, 10kg of urea and 12.5 -15kg of potassium chloride per mu.

When is the best time to control peanuts?

During the period from needling to pod setting, the high temperature and humidity will cause the growth of peanut. In order to control the vigorous growth, it should be sprayed with about 20g of strong and saturated fertilizer per mu and 40kg of water for 1 - 2 times from the late stage of needling to the early stage of pod setting, or when the height of main stem is 35cm-40cm. It not only controls the vigorous growth, but also controls the gibberellin biosynthesis in peanut plants, reduces cell division and elongation, i.e. inhibits the vegetative growth of aboveground parts, makes plants dwarf, thickens leaves, promotes the improvement of root activity, and improves the transportation and distribution of photosynthetic products. Therefore, it regulates physiological and biochemical functions, increases dry matter accumulation, improves quality and increases yield.

How to choose a peanut plantation

1. Peanut is a crop that blooms on the ground and bears fruit underground. The requirements for soil are loose tillage layer and thick sandy loam in living soil layer. However, yellow brown earth is suitable for black peanuts. According to Zhengyang soil survey, the soil structure of yellow brown earth plot with pod yield of more than 500kg per 1/15 hectare is more than 45cm of total soil thickness, mature tillage layer is about 30cm, pod bearing layer is soft loam layer.

2. Soil texture is clay layer below 10 cm;10cm-30cm is silty clay layer. such a soil structure has that advantage that capillary pores are small at the top and large at the bottom, non-capillary pore are large at the top and small at the bottom, the permeability of the upper layer soil is good, the water storage and fertilizer retention capacity of the low layer soil is strong, and the heat capacity is high, so that water, fertilizer, air and heat in the soil are coordinated and unified, and the peanut growth and pod formation are facilitated.

When are peanuts harvested?

Peanut harvest is improper, premature harvest pod is not full, shell tender seed kernel is too withered, resulting in yield reduction; harvest too late, fruit stalk, pod easy to fall off, not easy to harvest also resulting in yield reduction. When the leaves of the uppermost fruit branches of peanuts turn yellow, the night temperature is lower than 10℃, the shell network becomes clear and hard, and the seeds are ruddy, so that they can be harvested. At this time harvest, peanut pod full, fruit stalk constantly, pod is not easy to fall off, ensure high yield harvest high efficiency.

In the above, I also taught you some tips on peanut farming. Have you all learned it? Peanuts are relatively easy to grow. It is also very convenient to take care of, and the nutritional value of peanuts is also very high, so it is a kind of food suitable for all ages.
