Embodiment 1

[0032] The method for planting peanuts in saline-alkali soil based on straw mulching, salt suppression and seedling preservation, includes the following steps:

[0033] (1) Take the peanut variety as Huayu 25, select peanuts with full grains as seeds, and coat them before planting for use; before planting peanuts, level the ground, repair the ridges, perform fresh water irrigation, press salt, and water volume Control 90m 3 / Mu, keep the ground surface in a 1.5cm water layer for 1.5 days, and the soil water content reaches the saturated water content, so that the soil salinity of the cultivated layer is leached into the deep soil with water to achieve the purpose of compressed salt desalination;

[0034] (2) After irrigating water and pressing the salt, deep plow the soil and fine rake. When the water evaporates to the soil moisture content of 70%, the soil is plowed again and the base fertilizer is applied with 2000-3000 kg / mu of decomposed organic fertilizer and compound fertilize...

Embodiment 2

[0038] The peanut planting method in saline-alkali soil based on straw mulching, salt, salt, and seedling protection in this embodiment is the same as that in Example 1. The only difference is that in the step (3), the straw is covered on the sowing row and between the rows. fully cover.

Embodiment 3

[0040] The method for planting peanuts in saline-alkali soil based on straw mulching, salt suppression and seedling protection in this embodiment is the same as that in Example 1, except that the straw is also added with mushroom residue accounting for 5wt% of the straw mass (crushed to a particle size 5-15mm).

Abstract

The invention belongs to the technical field of crops planting, in particular to a method for planting peanuts in saline-alkali soil, based on straw mulching, salt inhibition and seedling preservation. Through the adoption of the method for planting peanuts in saline-alkali soil, based on straw mulching, salt inhibition and seedling preservation disclosed by the invention, after the peanuts are sowed in the saline-alkali land, previous-crop wheat straw is used for mulching the peanuts, so that increasing the seedling emergence rate of the peanuts is facilitated, growth development are promoted, leaf area indexes are increased, the crop covering degree is increased, and the purpose of alkali controlling and salt inhibition are achieved; and in general, a line spacing complete mulching manner of sowing lines is better than a half mulching manner of only mulching the sowing lines.

Description

Technical field [0001] The invention belongs to the technical field of crop planting, and specifically relates to a method for planting peanuts in saline-alkali soil based on straw mulching, salt suppression and seedling protection. Background technique [0002] The area of ​​saline-alkali soil in my country is about 1.0×10 7 hm 2 , Accounting for about 2.1% of the country’s total area and 6.2% of the arable land. At present, about 80% is still unused. Soil salinization seriously restricts food production and sustainable agricultural development. The Yellow River Delta is a typical area where soil salinization develops. Due to natural factors such as infertile soil and lack of fresh water resources, the Yellow River Delta has a simple plant community composition and a fragile ecological environment. Most plants cannot grow normally, and the vegetation coverage rate is low. The large amount of evaporation leads to the continuous accumulation of salt on the surface of the soil, and...
