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 o...

Embodiment 1

[0022] 1 Materials and methods

[0023] A field plot experiment was set up, the soil salt content in the 0-20cm soil layer was 0.308%, and peanuts / cotton were set up for intercropping in different ridges and flat cropping, repeated 3 times, and randomly arranged.

[0024] Peanut / cotton 2:1 equal width intercropping planting method:

[0025] (1) Soil preparation and salt pressing in spring

[0026] Before planting peanuts, carry out land leveling, fresh water irrigation and salt pressing, and the irrigation volume is 120-160m 3 per mu, keep the surface of the ground with a 1-2cm water layer for about 2 days, and the soil moisture content reaches the saturated moisture 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 desalination;

[0027] (2) Timely plowing and land preparation: after irrigation and salt pressing, plowing and land preparation are carried out when the water is evapo...

Abstract

The invention relates to the technical field of peanut planting and cultivation in saline and alkaline land, in particular to a cottonseed intercrop-planting method for achieving dual high peanut/cotton yields in saline and alkaline land. The method comprises the following steps that (a) land preparation and salt content restraining are performed; (b) timely ploughing and land preparation are performed; (c) fertilization is performed; (d) timely sowing is performed, wherein 4:2 equal-amplitude cottonseed intercropping mode is adopted for peanuts and cotton, and the floor area is kept to 1:1; (e) film covering is performed, wherein a convention planting and film covering planting mode is adopted. The yield level of cotton monoculture in a conventional mode is kept by adopting the equal-amplitude cottonseed intercropping mode, the peanut yield of 109-159 kg/mu is increased compared with monoculture peanuts (the yield is 170.5 kg/mu) in moderate-severe saline and alkaline land, the peanut yields of 50.76 kg/mu and 31.23 kg/mu are increased by adopting the 4:2 equal-amplitude cottonseed intercropping mode of peanuts/cotton compared with the yields obtained by adopting the proportions of 2:1 and 6:3, the anti-risk capability of an agricultural planting structure in the saline and alkaline land is improved, and the dual high peanut/cotton yields in the moderate or severe saline and alkaline land are achieved.

Description

technical field [0001] The invention relates to the technical field of peanut planting and cultivation in saline-alkali land, in particular to a cotton-oil intercropping planting method with double high-yield peanut / cotton 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, accounting for 6.2% of the cultivated 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-al...
