Problems solved by technology

The main reasons are, firstly, due to the low salt tolerance of peanut itself, it is not a salt-tolerant crop, and there are no varieties with strong salt tolerance; The structure is single and fragile, coupled with the time-consuming cotton labor, and its cost has risen in recent years, and its price and benefit have declined; third, peanuts are planted sporadically in saline-alkali land, with a small planting area, immature planting technology, and lack of seedlings caused by salt damage. The phenomenon is prominent, the output is very low, and the quality is poor
Therefore, the production area of ​​peanuts in saline-alkali land is small, the technology is low, the yield is unstable, and the economic benefits, social ecology and ecological benefits are low. However, peanuts have good economic benefits and light management. If the planting technology of peanuts in saline-alkali land can be improved, the yield , which is of great significance for improving the planting structure, increasing farmers' income and ensuring the safety of edible oils and fats

Embodiment 1

[0023] 1 Materials and methods

[0024] A field plot experiment was set up, the soil salinity of the 0-20cm soil layer was 0.308%, and the peanut / cotton intercropping between different ridges and rows was set to be flat-cropped with film, repeated 3 times, and arranged randomly.

[0025] Peanut / cotton 2:1 intercropping method:

[0026] (1) Spring soil preparation and salt pressure

[0027] Before peanut planting, carry out land leveling, freshwater irrigation and salt pressure, and the irrigation amount is 120-160m 3 / mu, keep the water layer of 1-2 cm on the surface for about 2 days, and the soil water content reaches the saturated water content, so that the soil salt in the plough layer is leached and infiltrated into the deep soil with water to achieve the purpose of salt pressure desalination;

[0028] (2) Timely ploughing and land preparation: after irrigation and salt pressure, ploughing and land preparation are carried out when the water evaporates to a soil moisture ...

Abstract

The invention relates to the technical field of planting and cultivation of peanuts in saline-alkali soil, in particular to a cotton-oil intercropping sowing method and planting method for high yield of peanuts and cotton in saline-alkali soil. According to the method, peanuts and cotton are sown in the saline-alkali soil with the soil salt content of 0.308% in the 0-20 cm soil layer, the peanuts and the cotton are intercropped in a 4: 2 equal-amplitude cotton-oil intercropping mode, namely, four rows of peanuts and two rows of cotton are intercropped, the occupied area is kept at 1: 1, and compared with single cropping peanuts (the yield is 170.5 kg / mu) in the moderate-severe saline-alkali soil, the yield of the peanuts is increased by 109-159 kg / mu, and the yield of the peanuts is increased by 109-159 kg / mu. According to the peanut / cotton 4: 2 equal-amplitude cotton-oil intercropping planting mode, the income of peanuts is increased by 50.76 kg / mu and 31.23 kg / mu compared with 2: 1 and 6: 3, the risk resistance of a saline-alkali soil agricultural planting structure is improved, and the double high yield of peanuts / cotton in moderate or severe saline-alkali soil is achieved.

Description

[0001] This application is a divisional application with an application date of December 19, 2016, an application number of 201611177751.6, and the title of the invention "A method for high-yield cotton-oil intercropping of peanut / cotton in saline-alkali land". technical field [0002] The invention relates to the technical field of planting and cultivation of peanuts in saline-alkali land, in particular to a cotton-oil intercropping seeding method and planting method with high yield of peanut / cotton in saline-alkali land. Background technique [0003] 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 cultivated land area. At present, about 80% of the land has not been used. Soil salinization seriously restricts the sustainable development of food production and agriculture. [0004] Peanut is an important oil crop and cash crop. Peanut oil is one of the main sources of vegetable oil. Peanut pl...
