Embodiment 1

[0024] In 2012, we sent Guangxi Ng Fung Machinery Co., Ltd. Fenlong unit to carry out Fenlong farming operations from Guangxi to Ningxia. According to Ningxia’s measurement of the Yellow River Irrigation to Pingjibao Modern Agricultural Demonstration Park of Nongken, the soil type is light gray calcium soil with medium soil fertility. The soil profile is divided into 3 layers. The average perennial cultivated layer is 20cm, the plow bottom layer is 10cm, and the loess layer is 20cm and 50cm. Sandy loam below. The measurement results showed that, compared with the control, the total salt content of the 0-20cm plow layer soil decreased by 56.48% before the Fenlong site preparation, and the total salt content of the 20-40cm plow layer increased by 68.89%; The total salt content of the 20cm plow layer soil decreased by 22.78%, and the total salt content of the 20-40cm plow layer decreased by 6.52%; 2 Increase production by 120.1kg. It shows that Fenlong cultivation has a good "l...

Embodiment 2

[0029] At the beginning of July 2013, the inventor organized a team to carry out powder ridge operations in the Hexi Corridor area of ​​Gansu. The total experimental area is 1000 mu, and corn is planted on the basis of the Fenlong operation. The following is the specific situation of the implementation:

[0030] Determination data of soil capacity, soil salinity and soil pH in the test site before Fenlong

[0031]

[0032] Corn shape, yield data results

[0033]

[0034] It can be seen that the soil quality in the cultivated area treated by the powder ridge tillage method has been significantly improved, the soil bulk density has dropped from 1.756 to 1.133, the salt content has been reduced from 0.161 to 0.102, and the pH has been reduced from 9.98 which is very unsuitable for crop growth to 7.10 The basic normal level shows that the powder ridge tillage method has a significant effect on improving the quality of the soil layer.

[0035] In addition, the growth of cor...

Abstract

The invention discloses a saline-alkali soil powder ridge light salt productive farming method. The method includes: performing powder ridge operation before ice and snow or rainy season in winter, wherein the operation is performed in two modes, namely whole field powder ridge and planting belt powder ridge 25-30cm and 30-40cm in farming depth respectively; cooperatively establishing escape canals; fertilizing. The problem that saline-alkali soil is not conductive to crop cultivation is effectively solved by the aid of measures of crop cultivation management and the like; meanwhile, soil environmental transformation is greatly benefited, operation concepts of utilization of original chemical methods and biological measures even soil changing are totally overthrown; the method is high in promotion value for 400-million mu of saline-alkali soil in China and has unexpected development prospects.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for cultivating high-yield and low-salt ridges in saline-alkali land. Background technique [0002] Soil salinization, also known as soil salinization or soil salinization, is the process in which soluble salts in the soil move to the surface with water and accumulate, so that the content of soluble salts (such as gypsum) exceeds 0.1% or 0.2%. Soil salinization causes soluble salts to accumulate in the soil, causing crops to fail to grow or be inhibited. These soluble salts are mainly: sodium chloride, sodium sulfate, sodium bicarbonate, sodium carbonate, etc. A large number of them make The rise of osmotic pressure in the soil solution makes it difficult for the crop roots to absorb water, commonly known as "flooded"; in addition, sodium bicarbonate and sodium carbonate are hydrolyzed in the soil solution to produce hydroxide ions, which makes the soil pH rise sharply a...
