Problems solved by technology

[0007] The sand water retention technology in the above patents is mainly used to irrigate farmland or plant trees; the lower layer of the lining film anti-seepage technology needs to dig trenches, and the efficiency is low when the trenches are deep; after the anti-seepage sand is laid, it will be destroyed during farming

Embodiment approach

[0032] The present invention can be used in the sandy land of the chestnut cinnamon area with uniform profile in a single row and double plant hole planting corn, and its implementation mode is as follows:

[0033] Step 1: Positioning. After the harvest of corn in the previous year (at the end of September or the beginning of October), the 4 holes were drilled according to the size of the farmland plot, and the center of each hole was marked with a wooden stick or a straw. 40cm, row spacing is 50cm.

[0034] Step 2: Take the topsoil. Before drilling hole 4, shovel out the 10cm-deep topsoil within the 410cm range of the drilling hole and place it on a piece of plastic film. The range of shoveling out is about 20cm from the center of drilling hole 4.

[0035] Step 3: Drill Hole 4. Utilize the trolley ground drill to carry out drilling 4 according to the marked position, the diameter of drilling 4 is 20cm, and the depth of drilling 4 is 80cm.

[0036] Step 4: Make the outer n...

Embodiment 2

[0041] Step 1: Positioning. After harvesting the previous crops in the autumn of last year (at the end of September or early October), drill holes 4 for positioning according to the size of the farmland plot. Insert a wooden stick or straw into the center of each hole for marking. The hole spacing is 40cm and the row spacing is 60cm.

[0042] Step 2: Take the topsoil. Before drilling hole 4, shovel out the 10cm-deep topsoil within the 410cm range of the drilling hole and place it on a piece of plastic film. The range of shoveling out is about 20cm from the center of drilling hole 4.

[0043] Step 3: Drill Hole 4. Utilize the trolley ground drill to carry out drilling 4 according to the marked position, the diameter of drilling 4 is 20cm, and the depth of drilling 4 is 80cm.

[0044] Step 4: Make the outer non-woven bag of the anti-seepage bag 1 ( figure 2 ). Make a double-layer anti-seepage bag outer layer non-woven fabric bag 1 with a diameter of 20cm (corresponding to ...

Abstract

The invention discloses a water retention method of a sand farmland, and belongs to the technical field of sand soil reclamation. The water retention method of the sand farmland comprises the following specific steps of: carrying out surface soil in-situ stripping, drilling holes for making pits, placing anti-seepage bags, and coating with a film around the holes for gathering water. The measures of drilling holes for making the pits, carrying out anti-seepage bag plantation and coating with the film around the holes are combined, a soil profile space structure of which the underground local water-resisting layer is coupled with ground surface local gathered water is formed in a dry farming farmland, while seepage of rainfall to deep soil is reduced, the rainfall is gathered to a crop plantation area, gathered rainwater is centralized and stored in a middle lower soil layer around a root system so as to be favorable for reducing ground surface evaporation and guaranteeing a crop water need requirement during drought, so that crop yield reduction amplitude caused by the drought is reduced, a better water retention and fertilizer maintenance effect is realized, meanwhile, all adopted materials are degradable materials, and solid waste, including straws and the like, can be effectively utilized.

Description

technical field [0001] The invention relates to the technical field of sandy land improvement, in particular to a sandy farmland water conservation method. Background technique [0002] Most of the farmland in northern my country is dry farming. Insufficient precipitation and lack of irrigation restrict the growth and yield formation of crops. Sandy soil is more likely to infiltrate water, causing serious water leakage and fertilizer leakage. It is difficult to maintain the soil in the root system of crops, making crops susceptible to drought. The technology of water conservation around the sandy farmland mainly includes technologies such as furrow preparation, soil surface film covering, mixing structure modifier, adding water retaining agent and lower soil lining film. The film can collect water around the surface of the hole, increase water storage around the root system of the lower layer, reduce water leakage and fertilizer leakage, and achieve drought resistance and hi...
