Problems solved by technology

Although this technology has many advantages, it can only be used for urban greening of saline-alkali flat land. If it is used for saline soil improvement of farmland, the cost of investment required by farmers is unacceptable. Therefore, a special technology for farmland saline soil improvement is invented. is very necessary

Embodiment 1

[0034] Embodiment 1: the comprehensive improvement method of salt-alkaline flat farmland soil and vegetation, it carries out soil improvement with a thickness of 0.4m on the ground surface on the plot to be improved, and specifically includes the following steps:

[0035] (1) Divide each plot to be improved into work blocks with a width of 20m and a length of several meters;

[0036] (2) Excavate the main blind ditch and branch ditch on the land to be improved. The main ditch is 0.3m×0.7m, and the branch ditch is 0.3×0.4; The ditch vertically intersects with the blind ditch of the branch water, which is in the shape of a fishbone; the main blind ditch is dug in the middle of each working section, and the two sides of each main ditch are to prevent the loss of natural rainfall Small square furrows, small square furrows should be made at every 10m on both sides of the main water blind ditch, and the soil moisture will be discharged into the branch water blind ditch according to ...

Embodiment 2

[0043] Embodiment 2: a method for comprehensive improvement of salt-alkaline flat farmland soil and vegetation, which carries out soil improvement with a thickness of 0.4m on the ground surface on the required improvement plot, and specifically includes the following steps:

[0044](1) Divide each plot to be improved into work blocks with a width of 20m and a length of several meters;

[0045] (2) Excavate the main blind ditch and branch ditch on the land to be improved. The main ditch is 0.3m×0.7m, and the branch ditch is 0.3×0.4; The ditch intersects vertically with the blind ditch of the branch water, which is in the shape of a fishbone: the main blind ditch is dug in the middle of each working section, and the two sides of each main ditch are to prevent the loss of natural rainfall Small square furrows, small square furrows should be made at every 10m on both sides of the main water blind ditch, and the soil moisture will be discharged into the branch water blind ditch acc...

Abstract

The comprehensive improvement method of soil and vegetation in saline-alkaline flat farmland is characterized in that it performs soil improvement with a thickness of 0.4m on the surface of the land to be improved, including dividing into blocks, digging the main ditch and branch ditch, Make small square plots to fill with clean stone salt, backfill the soil and level it, drill sand holes, make slopes, wash and discharge salt, fertilize and plow deeply. The advantage of the present invention is that the improved plot can have the growth of various crops and green turf, the growth of ground cover perennial flowers, forming a fertile soil suitable for planting turf and flowers of various food crops and shallow-rooted plants; less investment , a maximum investment of 5,000 per mu of land is enough, the improvement cost is greatly reduced, and the one-time investment can increase the efficiency forever, and can increase and expand my country's farmland planting area, effectively increasing my country's grain and vegetable production; protecting land resources and increasing food planting area; agricultural saline-alkali land has promoted an economical, broad-spectrum, simple, and indirect convenient technology.

Description

(1) Technical field: [0001] The invention relates to a method for comprehensive improvement of soil and vegetation, in particular to a method for comprehensive improvement of soil and vegetation in saline-alkali flat farmland. (two) background technology: [0002] At present, the area of ​​farmland saline-alkali land in our country is quite large and the range is also very wide, so it has a great impact on the growth of crops, directly affects the output of food and vegetables, and brings certain obstacles to economic development. [0003] In 2004, we applied for a patent named "Water-saving saline-alkali flat land physical-chemical-ecological comprehensive improvement and vegetation construction technology", the patent application number is 200410072547.9 (published by the State Intellectual Property Patent Office on May 3, 2006), And obtained considerable economic and social benefits. Because it can not only prevent the country's land from being destroyed, but also reduce...
