Problems solved by technology

[0003] The existing peanut planting method is ridge spacing 85-90cm, ridge surface width 55-60cm, ridge height 10-12cm, ridge width 30-32cm, film covering on the ridge, two rows of peanuts on the ridge, and peanut row spacing on the ridge 35-32cm. 40cm, 50cm between the ridges, if planted in saline-alkali land in this way, the yield is extremely low and cannot be cultivated normally

example 1

[0013] Test in 2011: the planting method adopts the technology of the present invention: the ridge distance is 43cm, the ridge height is 20cm, the ridge surface width is 16cm, the ridge is covered with film, the furrow width is 45cm, and two rows of peanuts are sown in the furrow with a row spacing of 35cm.

[0014] Prior art comparison: ridge distance 90cm, ridge height 10cm, ridge surface width 60cm, ridge width 30cm, film covering on the ridge, two rows of peanuts on the ridge, row spacing 40cm.

[0015] The results in Table 1 show that, compared with the control peanut, the invention can reduce the salt content of the peanut plow layer in saline-alkali land by 23.0% to 25.3%, increase the number of fruit per plant by 10.6 to 16.0%, reduce the number of kilograms of fruit by 6.8 to 15.7%, and achieve full fruit The yield and kernel yield increased by 2.6% to 6.7% and 2.2% to 3.5% respectively, and the yield increased by 30.4% to 35.8%.

[0019] Experimental invention technology in 2012: ridge spacing 45cm, ridge height 22cm, ridge surface width 19cm, ridges covered with film, ridge width 43cm, two rows of peanuts in the groove, row spacing 33cm.

[0020] Prior art comparison: ridge distance 87cm, ridge surface width 55cm, ridge height 12cm, ridge width 32cm, film covering on the ridge, two rows of peanuts sown on the ridge, row spacing 32cm.

[0021] The results in Table 2 show that, compared with the control peanut, the invention can reduce the salt content of the peanut plow layer in saline-alkali land by 24.8% to 28.8%, increase the number of fruits per plant by 13.8% to 14.3%, and reduce the number of fruits per kilogram by 2.9% to 3.7%. The full fruit rate and kernel yield increased by 4.7% to 7.3% and 3.6% to 4.7% respectively, and the yield increased by 22.4% to 38.9%.

Abstract

The invention discloses a high-yield method for cultivating peanuts in a saline-alkali land. The high-yield method for cultivating the peanuts in the saline-alkali land is characterized by comprising the following steps: ridging, wherein the ridge spacing is 42-45cm, the ridge height is 20-25cm and the ridge surface width is 15-20cm; laminating ridges, wherein the furrow width is 42-45cm; sowing two rows peanuts into each furrow at a row spacing of 32-35cm. By the high-yield method, the peanuts are planted in the saline-alkali land; the salt content of a peanut cultivating layer in the saline-alkali land is reduced by 23.0-28.8%; the fruit number per plant can be increased by 10.6-16.0%; the fruit number per kilogram is reduced by 6.8-15.7%; the full fruit rate and the kernel rate are increased by 2.6-7.3% and 2.2-4.7% respectively; the yield is increased by 22.4-38.9%.

Description

technical field [0001] The invention relates to a high-yield cultivation method for peanuts in saline-alkali land, which belongs to the technical field of agricultural planting. Background technique [0002] Soil salinization is a serious problem affecting agricultural production and ecological environment. About 50% of the cultivated land in the world is harmed by salt stress, and the saline-alkali land area in my country reaches 1.5 billion mu. Peanut is the main oil crop and economic crop in our country. With the increase of population, the increase of demand, the continuous decline of cultivated land, the conflict of grain and oil competition for land has become increasingly prominent. How to develop and utilize salinized land resources is of great significance. [0003] The existing peanut planting method is ridge spacing 85-90cm, ridge surface width 55-60cm, ridge height 10-12cm, ridge width 30-32cm, film covering on the ridge, two rows of peanuts on the ridge, and pe...
