Problems solved by technology

[0003] However, since Jilin Province is located in an alpine region, the average daily temperature is higher than 12°C in mid-to-late May, which is later than other low-latitude areas. The peanut sowing period is later, and the sowing is slightly earlier. When encountering cold currents, large areas of low-temperature rotten seeds will occur. and the flowering and needle stage are often threatened by low temperature and chilling damage, which has a great impact on the growth process and yield of peanuts

Embodiment 1

[0028] The planting test base is in Gongzhuling City, Jilin Province, and the land with deep soil layer, fertile cultivated layer and flat terrain is selected.

[0029] The invention provides a cultivation process for improving the low temperature resistance of peanuts, which comprises the following production steps:

[0030] Step 1: Soil preparation, ridge making, and fertilization: plow to a depth of 20 cm, and use the rotary plow and harrow to achieve deep, loose, fine, broken, flat, no weeds, no root stubble and timely ridges; autumn culling Ridges, the distance between the ridges is 60cm. Fertilizer is applied once as base fertilizer, every 666.7m 2 Use 50kg of bio-organic fertilizer after composting and 15kg of peanut peel, then add 15kg of urea, 15kg of potassium sulfate, 35kg of superphosphate, and 8kg of calcium oxide.

[0031] Step 2: Seed treatment: Peanuts are sun-dried for 2-3 days before shelling, shelled 7-10 days before sowing, and insects, buds, and rotten f...

Embodiment 2

[0044] The planting test base is in Gongzhuling City, Jilin Province, and the land with deep soil layer, fertile cultivated layer and flat terrain is selected.

[0045] The invention provides a cultivation process for improving the low temperature resistance of peanuts, which comprises the following production steps:

[0046] Step 1: Soil preparation, ridge making, and fertilization: plow to a depth of 25 cm, and use the rotary plow and harrow to achieve deep, loose, fine, broken, flat, no weeds, no root stubble, and timely ridges; autumn ploughing Ridges, the distance between the ridges is between 60cm. Fertilizer is applied once as base fertilizer, every 666.7m 2 Use 50kg of bio-organic fertilizer after composting, 15kg of peanut peel, 15kg of urea, 15kg of potassium sulfate, 25kg of superphosphate, 5kg of calcium oxide, and fertilization depth of 10cm;

[0047] Step 2: Peanuts are sun-dried for 3 days before shelling, shelled 7 days before sowing, and insects, buds, and r...

Abstract

The invention discloses a cultivation process for improving low-temperature resistance of peanuts, and particularly relates to the technical field of peanut cultivation. The cultivation process for improving low-temperature resistance of the peanuts comprises the following steps that step 1, soil preparation, ridging and fertilization are conducted; step 2, seed treatment is conducted; step 3, sowing is conducted; step 4, field management is conducted; and step 5, harvesting and airing are conducted. According to the cultivation process for improving low-temperature resistance of the peanuts, by additionally applying phosphate fertilizer, seed coating agent coating and peanut peel, peanut seeding time can be advanced, the pollination rate can be increased in the flowering period, harvesting can be performed in advance, the peanut seeding time is advanced by 3-5 days, the emergence rate is ensured to be 97% or above, the maturity of pods can be increased, and the yield can be increased by 35%-43% or above; meanwhile peanut peel powder is used in cooperation with the seed coating, the peanut peel powder is evenly dispersed on the outer side of the seed coating, the peanut peel powder is fermented underground to generate trace heat, the heat preservation and insulation effect of the seed coating can be effectively enhanced, the low temperature resistance of the peanuts is improved, the seeding time can be advanced through the coating during spring seeding, and the maturity of the pods is increased.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, more specifically, the invention relates to a cultivation technique for improving the low temperature resistance of peanuts. Background technique [0002] Low temperature is the main natural disaster during the sowing period of peanut planting areas in Jilin Province. Every occurrence of low temperature and chilling damage will cause a large area of ​​peanut production reduction. During planting, peanuts will fail to germinate or rot due to low temperature weather, affecting the whole seedlings; The seedlings will also die due to cold damage, which seriously affects the yield and quality. Peanut production not only shoulders the important task of ensuring the safety of edible oil in our country, but also shoulders the important mission of adjusting the agricultural planting structure and increasing farmers' income. Therefore, large inter-annual fluctuations in peanut production in Nor...
