Embodiment 1

[0022] 1 Materials and methods

[0023] 1.1 Test varieties

[0024] Select the salt-alkali tolerant peanut varieties Huayu No. 22, Huayu No. 25 and Huayu No. 36.

[0025] 1.2 Method

[0026] A field experiment was set up, the soil salt content in the 0-20cm soil layer was 0.287%, and the soil salt content in the 20-40cm soil layer was 0.234%. Two treatments were set up: flat sowing without mulching and ridge cropping with mulching, repeated 3 times, and randomly arranged.

[0027] Ridge filming:

[0028] (1) Land preparation and salt pressing in spring: Before peanut planting, level the land, repair ridges and ditches, and carry out fresh water irrigation to press salt, with an irrigation volume of 145m 3 per mu, keep the 1.5cm water layer on the surface for 1.5 days, and the soil water content reaches the saturated water content, so that the soil salinity in the plow layer can be leached and infiltrated into the deep soil with water to achieve the purpose of salt desalinat...

Embodiment 2

[0051] 1 method

[0052] A field experiment was set up, the soil salt content in the 0-20cm soil layer was 0.287%, and the soil salt content in the 20-40cm soil layer was 0.234%. Four treatments were set up, all of which were planted with ridge cropping and film mulching, as follows:

[0053] Handling one:

[0054] (1) Land preparation and salt pressing in spring: Before peanut planting, level the land, repair ridges and ditches, and perform fresh water irrigation to press salt, with an irrigation volume of 140m 3 per mu, keep the 2cm water layer on the surface for 1 day, and the soil water content reaches the saturated water content, so that the soil salinity in the plow layer can be leached and infiltrated into the deep soil with water to achieve the purpose of desalination.

[0055] (2) Fertilization: After watering and pressing salt, soil plowing and fertilization will be carried out when the water evaporates to a soil moisture content of 80%. Fertilization amount: decomp...

Abstract

The invention relates to a ridge planting film mulching planting method for increasing the yield of peanuts in the saline and alkaline land. The ridge planting film mulching planting method includes the steps that firstly, land preparation and salt restraining are conducted, namely land formation, furrow trimming and fresh water irrigation are conducted before the peanuts are planted, and a 1-2 cm water layer is kept on the earth surface for 1-2 days, wherein the irrigation amount ranges from 140 cubic meters per mu to 150 cubic meters per mu; secondly, fertilizer application is conducted, namely after irrigation and salt restraining, when the soil moisture content ranges from 60% to 80% through moisture evaporation, ploughing and fertilizer application are conducted; thirdly, ridging and sowing are conducted, namely the peanuts are sown when the earth temperature of the 0-10 cm soil layer ranges from 13 DEG C to 17 DEG C, and the planting density is kept from 14,000 hills per mu to 15,000 hills per mu, wherein the height of ridges ranges from 18 cm to 22 cm, the width of ridge surfaces ranges from 55 cm to 60 cm, and the distance between the ridges ranges from 70 cm to 75 cm; fourthly, film mulching is conducted, namely films are mulched on the ridges and covered with soil in time. According to the planting method, the soil salt content of the 0-40 cm surface layer is obviously reduced after the peanuts grow into the fruiting period, and eventually the yield of the peanuts in moderate and slight saline and alkaline land is greatly increased.

Description

【Technical field】 [0001] The invention relates to the technical field of peanut planting and cultivation, in particular to a ridge-planting and film-covering planting method for improving the yield of peanuts in saline-alkali land. 【Background technique】 [0002] The area of ​​saline-alkali soil in my country is about 1.0×10 7 hm 2 , accounting for 2.1% of the total land area and 6.2% of the arable land area, about 80% of which have not yet been utilized. Soil salinization seriously restricts the sustainable development of food production and agriculture. [0003] Peanut is an important oil crop and economic crop. Peanut oil is one of the main sources of vegetable oil. Peanut plays an important role in China's agricultural development and export earnings. According to previous statistics and research, my country's peanut area is about 80 million mu, 80% of which are distributed on dry and thin land, and almost no peanuts are planted on saline-alkali land. The main reasons...
