Embodiment 1

[0041] Low-cost treatment method for soil salinity in greenhouse fruit trees

[0042] The processing method steps are as follows:

[0043] Step S10, soil treatment: After the fruit trees 10 are picked in autumn, basal fertilizer is applied to the rows of the fruit trees 10 in order, winter water is poured, and the land between the rows is leveled;

[0044] Step S20, preparation of vermiculite: 3~5m per mu 3 Purchase vermiculite for cultivation. The vermiculite has a particle size of 1-3mm, a hardness of 1.2-1.4, and a bulk density of 1450kg / m. 3 ;

[0045] Vermiculite is a natural and non-toxic mineral. Its crystal structure is monoclinic. It has the ability of ion exchange. It will expand after low-temperature roasting. In addition, low-temperature roasting can remove volatile substances in vermiculite, which greatly increases Its internal surface area and rich internal surface area make it easier for the saline molecules impregnated in the soil to adhere to it, which improves the ef...

Abstract

The invention discloses a low-cost treatment method for soil salt and alkali of fruit trees in a greenhouse. The method specifically comprises the steps of treating soil, preparing vermiculite, covering mulching film, laying the vermiculite and replacing the vermiculite. Through the adoption of the low-cost treatment method for the soil salt and alkali of the fruit trees in the greenhouse, by utilizing a physicochemical improvement method and an agglomeration siphon technology, the oriented migration and concentrated removal of saline and alkaline components in the soil are achieved; not only is the improvement of the soil salt and alkali achieved, but also the salinization of the soil can be alleviated in future agricultural production.

Description

Technical field [0001] The invention belongs to the technical field of soil improvement, and particularly relates to a low-cost treatment method for soil salinity in greenhouse fruit trees. Background technique [0002] According to statistics, the area of ​​saline soil in my country is about 3.69×10 7 hm 2 , The area of ​​arable land salinization is 7.6×10 6 hm 2 , The land acquisition area of ​​saline-alkali emperor and saline-alkali barrier with agricultural utilization potential is nearly 1.3×10 7 hm 2 Nearly one-fifth of the arable land has been salinized. The salt in the soil of saline-alkali arable land is very harmful to the root system of crops. After the root system of crops is poisoned by salt, the root system is poorly developed and prematurely aging. There is a lot of salt in the soil of saline-alkali soil, and there are often white salt-alkali deposits on the soil surface, poor ventilation and water permeability, and crop roots are often poisoned, rotten, and dead. E...
