Key points of high-yield cultivation techniques of peanut

Before the seed is planted, it should be shelled and sun-dried before planting. Choose sunny day in the morning, spread about 10 centimeters thick, turn it once every 1-2 hours, and soak for 2 to 3 days. The time for shelling is preferably 10 to 15 days before sowing. After shelling, the kernels are large and tidy, the seeds are full, the color is good, and the primary and secondary large seeds are not damaged by mechanical damage, and the tertiary particles are eliminated.
Soil improvement and deep cultivation of peanuts is the result of the underground flowering of the ground, the root system is developed, the soil layer is required to be deep, and the upper part is loose, so it is necessary to properly plow the deep plan before winter or early spring. For the clay soil, an appropriate amount of fine sand can be added to improve the permeability of the resulting soil layer. The sand layer is too thick, and the result is deep. The clay is 10-15 cm thick under the plow to create a soil layer for water storage and fertilizer conservation.
Rising and mulching, cultivating soil strength Because the number of nodules in the early stage of peanut growth is small, the nitrogen fixation ability is weak, and the fruit needle has been inserted into the soil in the middle and later stages, which is not suitable for fertilization. Therefore, it is very important to apply the base fertilizer to the peanut. Generally, before planting, combine the ploughing and land preparation, and apply the base fertilizer at one time to meet the demand for fertilizer in the whole growth period. As far as possible, the farmer's fertilizer should be applied as much as possible in the conditional areas. The farmer's fertilizer should be 2,000-3,000 kg per mu of the base, 30-40 kg of compound fertilizer, 30 kg of boron fertilizer, and 1 kg of boron fertilizer. The high-yield field should be 3,000-4,000 kg of farmyard manure per mu. 45% compound fertilizer 40 ~ 50 kg, boron fertilizer 1 ~ 1.5 kg. In addition, peanuts are not recommended to apply seed fertilizers, especially when boron fertilizer is used as base fertilizer, it is strictly prohibited to be applied into the seeding ditch to avoid burning seedlings.
Appropriate sowing, the whole seedling strong seedling 5 cm soil temperature is stable at 12 ° C, generally can be half an earlier than bare land cultivation. April 20 to May 5. Large ridges and double rows, the distance between the holes is 16 to 18 cm, 8,000 to 10,000 holes per mu, 2 seeds per hole; 3 to 4 cm deep.
In the early stage of field management (seed period), management should be strengthened, roots should be tied, pests and diseases should be prevented, and early seedlings should be promoted.
In the middle stage (flower needle-result period), it mainly controls the growth of branches and leaves above the ground, and promotes the development of fruit needles and young fruits below. The late stage (mature period) is the period of full bloom of pods, which mainly reflects the word “post-protection”. It pays attention to drought-resistant and sputum-sucking to prevent rotten fruit, and to control insects and fruit to win high yield, prevent disease and protect leaves and promote fruit.
