Embodiment 1

[0017] Embodiment 1: a kind of saline-alkali land improvement high-yield cultivation method of the present invention specifically comprises the following steps:

[0018] (1) Before the rain or ice and snow, use the rotary tillage screw machine to deep-rotate the powder ridge on the saline-alkali land, that is, to loosen the deep ditch on the saline-alkali land, and use the machine to cut the land horizontally at the same time, in order to avoid the deep soil from moving up and causing the land to rot. When the depth of saline-alkali soil reaches a certain level, it must be ridden naturally;

[0019] (2) Establish drainage channels on the edge of the strip behind the Fenlong, and use rainwater or snowwater to dilute the excessively high salinity of the land;

[0020] (3) Dilute the green manure nutrient solution brewed by the three-in-one starter with 100 times of water and water it after the rain or snow;

[0021] (4) After the nutrient solution is irrigated, apply fertilizer...

Embodiment 2

[0025] Embodiment 2: a kind of saline-alkali land improvement high-yield cultivation method of the present invention specifically comprises the following steps:

[0026] (1) Before the rain or ice and snow, use the rotary tillage screw machine to deep-rotate the powder ridge on the saline-alkali land, that is, to loosen the deep ditch on the saline-alkali land, and use the machine to cut the land horizontally at the same time, in order to avoid the deep soil from moving up and causing the land to rot. When the depth of saline-alkali soil reaches a certain level, it must be ridden naturally;

[0027] (2) Establish drainage channels on the edge of the strip behind the powder ridge, and use rainwater or snowwater to dilute the excessively high salinity and alkali components of the land and bring them into the deep soil;

[0028] (3) Dilute the green manure nutrient solution brewed by the three-in-one starter with 100 times of water and water it after the rain or snow;

Abstract

The invention discloses a saline land improvement and high-yield cultivation method. The method comprises the specific steps that before rainwater or ice and snow is introduced, a rotary tillage spiral type machine is used for carrying out smashing and ridging and deep rotating on a saline land, namely, deep furrow loosening is carried out on the saline land, the machine is used for smashing soil while transversely cutting the land, and in order to avoid damage to the land due to upper moving of the soil of a deep layer, natural ridging is carried out when the soil in the saline land is deeply rotated to a certain degree; water drain channels are built in the land area edges after smashing and ridging are carried out, and the rainwater or snow water is utilized for diluting excessive salt and alkali in the soil and bringing the salt and the alkali into the soil of the deeper layer. Realization of the land improvement method has great significance in solving the problem of huge waste of land resources in China, the problem of shortage of grain can be effectively solved, the environment can be improved, and the method brings good economic benefits and is wide in development prospect.

Description

technical field [0001] The invention relates to a method for improving agricultural land, in particular to a method for improving high-yield cultivation of saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem. The soil in saline-alkali land is compacted, and only some saline-alkali grasses grow, but no crops and crops, which is a great waste of land resources. my country has 99.13 million hectares, or about 1.47 billion mu, and nearly 100 cities across the country are located in saline-alkali land distribution areas. Nearly 500 million mu of farmland has been lost or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuous expansion of salinized and...
