[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 located in Gongzhuling City, Jilin Province, and a plot with deep soil layer, fertile ploughing layer and flat terrain is selected.
[0029] The invention provides a cultivation technique for improving the low temperature tolerance of peanut, comprising the following production steps:
[0030] Step 1: soil preparation, ridge making, and fertilization: tilling depth of 20cm, use rotary tillage plows and harrows with the cultivated land to achieve deep, loose, fine, broken, flat, no weeds, no previous stubble and timely ridge formation; Ridge, the ridge distance is 60cm. Fertilizer is applied once as base fertilizer, every 666.7m 2 With 50kg of bio-organic fertilizer and 15kg of peanut peel after composting, then add 15kg of urea, 15kg of potassium sulfate, 35kg of superphosphate, and 8kg of calcium oxide, and set the test control group without superphosphate simultaneously, and the depth of fertilization is 15cm;

Embodiment 2
[0044] The planting test base is located in Gongzhuling City, Jilin Province, and a plot with deep soil layer, fertile ploughing layer and flat terrain is selected.
[0045] The invention provides a cultivation technique for improving the low temperature tolerance of peanut, comprising the following production steps:
[0046] Step 1: soil preparation, ridge making, and fertilization: plowing depth of 25cm, and using rotary tillage plows and harrows with the cultivated land to achieve deep, loose, fine, broken, flat, no weeds, no previous stubble and timely ridge formation; Ridge, ridge distance between 60cm. Chemical fertilizer is applied as base fertilizer once, every 666.7m 2 After composting, 50kg of bio-organic fertilizer and 15kg of peanut peel, 15kg of urea, 15kg of potassium sulfate, 25kg of superphosphate, 5kg of calcium oxide, and 10cm of fertilization depth;
[0047] Step 2: The peanuts are sun-dried for 3 days before peeling, and the shells are peeled 7 days befor...

Abstract
The invention discloses a cultivation process for improving peanut low temperature resistance, and specifically relates to the technical field of peanut cultivation, including step 1: soil preparation, ridge making, and fertilization; step 2: seed treatment; step 3: sowing; step 4: field management; Step 5: Harvest and dry. The present invention can advance the sowing period of peanuts, increase the pollination rate at the flowering period and harvest in advance by increasing the application of phosphorus fertilizer, seed coating agent coating and peanut peel, advance the sowing period of peanuts by 3 to 5 days, ensure that the emergence rate is above 97%, increase the The maturity of pods can increase the yield by more than 35% to 43%. At the same time, the peanut peel powder is used in conjunction with the seed coating. The peanut peel powder is evenly scattered on the outside of the seed coating. Effectively strengthen the thermal insulation effect of seed coating, improve the ability of peanuts to withstand low temperature, and can advance the sowing date through coating during spring sowing, and increase the maturity of pods.
Description
technical field [0001] The invention relates to the technical field of peanut cultivation, and more particularly, to a cultivation process for improving the low temperature tolerance of peanuts. Background technique [0002] Low temperature is the main natural disaster during the planting period of peanut planting areas in Jilin Province. Every occurrence of low temperature and chilling damage will cause a large area of peanut yield. During planting, peanuts will fail to germinate or rot due to low temperature weather, which will affect the whole seedling; The seedlings will 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 my country, but also shoulders the major mission of adjusting the agricultural planting structure and increasing farmers' income. Therefore, the large inter-annual fluctuation of peanut yield in Northeast China will inevitably lead to th...
