Problems solved by technology

However, this improvement method generally has no harvest in the first year, and can only be harvested after repeated 3-4 years, and the input cost is high-it is estimated that the development cost of saline-alkali land is nearly 20,000 yuan / ha, and the development and utilization of saline-alkali land is not casual. Can do, and the present invention just introduces a kind of method that utilizes ice vegetable to improve saline-alkali land with low cost

Embodiment 1

[0022] A method of using ice vegetable rotation to assist in solving soil salinization, the method comprising the following steps:

[0023] 1) Stir the wet seedling substrate and ice vegetable seeds evenly and sprinkle them into the flat tray substrate. The seeding rate is 1.1g / ㎡, and then cover with another layer of substrate. The covering principle is to cover the seeds, then spray water, and finally Lay plastic film, and the seedling temperature is 17°C;

[0024] 2) When the ice vegetable seedlings grow a pair of leaves, transplant them into the seedling trays with 50 or 72 holes. During the transplanting process, ensure that the roots of the ice vegetable seedlings are taken out together with the matrix, and the growth temperature at the seedling stage is 21°C;

[0025] 3) When the ice vegetable seedlings grow 4-6 leaves, they can be planted. 6 days before planting, place 16g of phosphate fertilizer in each seedling tray, and pour an appropriate amount of water to dissolve...

Embodiment 2

[0035] A method of using ice vegetable rotation to assist in solving soil salinization, the method comprising the following steps:

[0036] 1) Stir the moist seedling raising substrate and ice vegetable seeds evenly and sprinkle them into the flat tray substrate. The seeding rate is 1.2g / ㎡, and then cover with another layer of substrate. The covering principle is to cover the seeds, then spray water, and finally Laying plastic film, the seedling temperature is 18 ℃;

[0037] 2) When the ice vegetable seedling grows a pair of leaves, transplant it into a 50 or 72-hole seedling tray. During the transplanting process, ensure that the root of the ice vegetable seedling is taken out with the adhesive matrix, and the growth temperature at the seedling stage is 23°C;

[0038] 3) When the ice vegetable seedlings grow 4-6 leaves, they can be planted. 7 days before planting, place 18g of phosphate fertilizer in each seedling tray, and pour an appropriate amount of water to dissolve the ...

Embodiment 3

[0048] A method of using ice vegetable rotation to assist in solving soil salinization, the method comprising the following steps:

[0049] 1) Stir the wet seedling raising substrate and ice vegetable seeds evenly and sprinkle them into the flat tray substrate, the seeding rate is 1.3g / ㎡, and then cover with another layer of substrate. The covering principle is to cover the seeds, then spray water, and finally Laying plastic film, the seedling temperature is 19 ℃;

[0050] 2) When the ice vegetable seedling grows a pair of leaves, transplant it into a 50 or 72-hole seedling tray. During the transplanting process, ensure that the root of the ice vegetable seedling is taken out with the sticky matrix, and the growth temperature at the seedling stage is 25°C;

[0051]3) When the ice vegetable seedlings grow 4-6 leaves, they can be planted. 8 days before planting, put 20g of phosphate fertilizer in each seedling tray, and pour an appropriate amount of water to dissolve the phospha...

Abstract

The invention discloses a method for solving soil salinization through assistance of mesembryanthemum crystallinum crop rotation. The method comprises the steps that a damp seedling raising medium andmesembryanthemum crystallinum seeds are evenly stirred and spread into a flat tray medium, the sowing amount is 1.1-1.3 g / m<2>, a layer of medium is used for covering, based on a covering principle,the seeds are covered with the medium, then water spraying is conducted, finally, a mulching film is laid, and the seedling raising temperature is 17-19 DEG C. According to the method, mesembryanthemum crystallinum is planted in a field with soil salinization, through a crop rotation planting method, agricultural diversified development is achieved, a salt excretion plant mesembryanthemum crystallinum is used for absorbing salt in the soil, the salt is discharged out of the soil, salt transfer in the soil is achieved, and the salinity and alkalinity of the soil are improved; during planting ofthe mesembryanthemum crystallinum, through seedling raising and two-time seedling transplantation, field planting is conducted, the survival rate of the mesembryanthemum crystallinum is greatly increased, and the salinity and alkalinity of the soil are improved to the greatest degree.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for assisting in solving soil salinization by utilizing ice vegetable rotation. Background technique [0002] Salt, like air and water, is an essential element for human beings to maintain life. But salt is not harmless. Saline-alkali land is harmed by salt, and "alkali" is also called "cancer" of the soil. Saline-alkali land, in the eyes of many people, is a barren land. Saline-alkali land affects the normal growth of crops, and the yield of crops is extremely low, or even no grass grows. [0003] Statistics show that at present, there are 8.4 million square kilometers of salinized land in the world, distributed in 112 countries and regions, from frigid, temperate to tropical regions, from America, Europe, Asia to Australia, there are a lot of salty land everywhere. , Dry, hardened, barren saline-alkali land, due to improper irrigation, precipitation and oth...
