Problems solved by technology

The emergence of a large number of saline-alkali lands has caused crop yield reduction and plant reduction, which is not conducive to the development of national agriculture and greening
[0004] The current characteristics of saline-alkali land make the survival rate of seedlings low, and the use of existing organic fertilizers has no obvious improvement effect on saline-alkali land
[0005] The inventors have learned that most of the existing cultivation devices simply mix commercially available fertilizers wit...

Embodiment 2

[0054] A slow and controlled release water retention cultivation method for alkaline soil, comprising the following steps:

[0055] Making support carrier 1 and air-permeable carrier 4 by using organic crop fertilizer;

[0056] Digging pits in alkaline soil, filling the support carrier 1, air-permeable carrier 4 and cultivation area carrier 3;

[0057] Fill the cavity of the support carrier 1 with a water-absorbing material 7, attach a breathable and water-permeable film to the wall of the support carrier 1 near the first tank, and attach a breathable and water-permeable film to the wall of the support carrier 1 near the external soil;

[0058] Plant seedlings at carrier 3 in the cultivation area;

[0059] When the carrier 3 in the cultivation area lacks water, the water-absorbing material 7 supplies water, and when the carrier 3 in the cultivation area has too much water, the water-absorbing material 7 stores water;

[0060] During the growth of plant seedlings, the organic...

Abstract

The invention relates to a sustained and controlled release water retention cultivation device and method for alkaline soil. The sustained and controlled release water retention cultivation device comprises a supporting carrier, a first groove body is formed in a middle part of an upper surface of the supporting carrier, the first groove body is filled with a breathable carrier, the breathable carrier is of a porous structure, the breathable carrier is filled with an organic fertilizer, a second groove body is formed in a middle part of an upper surface of the breathable carrier, a cultivation area carrier is arranged in the second groove body and used for planting to-be-cultivated plants, a breathable and water-permeable film is arranged on an inner wall face of the first groove body, a breathable and water-impermeable film is arranged on an adjacent side face of the supporting carrier and the external soil, an inner cavity is formed in the supporting carrier, and a water absorption material is arranged in the inner cavity.

Description

technical field [0001] The disclosure belongs to the technical field of environmental protection equipment, and in particular relates to a slow-controlled release and water-retaining cultivation device and method for alkaline soil. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] China is a big country with saline-alkali land. The saline-alkali land has a large area, wide distribution, and a large proportion of cultivated land. The salt content in the soil is too high and the crops cannot grow normally. According to UNESCO and the Food and Agriculture Organization of the United Nations Incomplete statistics show that the area of ​​saline-alkali land in the world exceeds 950 million hectares, of which the area of ​​saline-alkali land in my country accounts for about 10%. The emergence of a large number of saline-alkali lands has caused crop yield re...
