Problems solved by technology

The main reasons are, first, that peanuts are not salt-tolerant crops due to their low salt tolerance, and there are no varieties with strong salt tolerance; Peanuts are planted sporadically in saline-alkali land, the planting area is small, the planting technology is immature, and the phenomenon of lack of seedlings and ridges caused by salt damage is prominent, the yield 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 output is unstable, and the economic benefits, social ecology and ecological benefits are low

Embodiment 1

[0036] Embodiment 1: the method for planting peanuts in saline-alkali land:

[0037] (1) Before sowing, apply pesticides in the saline-alkali soil, and use the sun to expose the farmland for 3 days, so as to fully kill the pests and grass crops that have been applied with pesticides;

[0038] (2), cast special improving agent in saline-alkali land, wherein, fermented fern 150kg / mu, phosphogypsum 200kg / mu, ammonium chloride 50kg / mu, and utilize rotary tiller to rotate the farmland exposed to the sun, Fully mix the applied amendment with the soil, water to make the soil sufficiently wet, and allow the soil to ferment and react for 7 days.

[0039] (3), sowing: use peanut seeder to drill holes for direct seeding, use 20kg of high-quality and high-yield peanut seeds per mu, sow two rows on the ridge, the width of the small row is 20 centimeters, two seeds per litter, and the sowing depth is 2 centimeters.

[0040] (4), Topdressing: Regularly apply nitrogen fertilizer 4kg / mu an...

Abstract

The invention provides a method for planting peanuts in saline-alkali soil. The method for planting the peanuts in the saline-alkali soil is easy to operate, organic fertilizer such as industrial waste residue ardealite and fermented ferns is applied to the soil, the applying and planting cost is low, the soil properties of the saline-alkali soil can be improved, the PH value of the soil is lowered, and the total salt content of the soil is also lowered; moreover, the soil can be made to be rich in nutrients needed by growth of various crops; in particular, the method is quite suitable for growth of the peanuts, and therefore the yield of the peanuts can be greatly increased and the quality of the peanuts can be greatly improved.

Description

technical field [0001] The invention relates to an agricultural technology, in particular to a method for planting peanuts in saline-alkali land, and belongs to the field of agricultural technology. Background technique [0002] my country is a large country with a population of 1.3 billion, and its per capita land resources are lower than the world average. The serious shortage of land resources, coupled with poor land quality, has been restricting the development of my country's agriculture. my country has a large amount of saline-alkali land, with an area of ​​99.13 million hectares. It is mainly distributed in Northwest China, North China, Northeast West and coastal areas. production potential. Transformation, management and rational development and utilization of these resources are one of the important ways for the sustainable development of China's agriculture, and they are also of great significance to improving the ecological environment and promoting the sustainab...
