Problems solved by technology

The measures for controlling saline-alkali land in the prior art generally include water conservancy improvement, physical improvement, biological improvement and chemical improvement. As the soil salinity varies in different regions, the application of each measure has its shortcomings or deficiencies, and the improvement effect is not ideal, for example The water conservancy method adopts slow irrigation, leaching, washing and desalting, which not only consumes a lot of fresh water resources, but also has high cost, while the physical, chemical and biological improvement methods have single effect and slow effect
On the other hand, excessive salt can cause crops to produce various physiological and metabolic failures, such as stomatal closure disorders and egg formation being blocked, while the saline-alkali soil improvement methods in the prior art only focus on soil improvement measures, and ignore how to solve the problem of crops in the soil. The failure of various physiological metabolisms in saline-alkali land, therefore, how to enhance the salt resistance and stress resistance of crops is also a technical problem that needs to be solved

Embodiment 1

[0064] In Xihonggangzi Village, Da'an City, Jilin Province, the saline-alkali land was improved and 10 mu of rice was planted. The rice variety was Baijing No. 1. The soil belongs to the heavy soda saline-alkali land of the Songnen Plain. The soil EC value is 1.3ms / cm, and the soil pH is 9.5. The saline-alkali land is not treated with soaking and salt-washing, and the soil and planting plans for improving the saline-alkali land include: soaking seeds, applying basal fertilizer, applying top-dressing fertilizer, and spraying biological pesticides.

[0065] 1. Seed soaking

[0066] After diluting according to the mass ratio of Fuhuanong to water of 1:200, then according to the diluted Fuhuanong to seed mass ratio of 1:1, soak the seeds for 2 hours, then place the soaked seeds in a cool place to dry, and then dry Back up the bag.

[0067] Second, the application of basal fertilizer

[0068] The dosage of soil conditioner is 1000 kg per mu, and the amount of bio-organic fertiliz...

Embodiment 2

[0080] In Qiaojia Village, Changling County, Songyuan, Jilin Province, the saline-alkali land was improved and 5 mu of black beans were planted. The land was barren and highly alkaline, the soil EC value was 1.1ms / cm, and the soil pH was above 9. The saline-alkali land is not treated with soaking and salt-washing, and the soil and planting plans for improving the saline-alkali land include: soaking seeds, applying basal fertilizer, applying top-dressing fertilizer, and spraying biological pesticides.

[0081] 1. Seed soaking

[0082] After diluting according to the mass ratio of Fuhuanong to water of 1:200, and then according to the diluted Fuhuanong to seed mass ratio of 1:0.5, soak the seeds for 6 hours, and then place the soaked seeds in a cool place to dry. Back up the bag.

[0083] Second, the application of basal fertilizer

[0084] The dosage of soil conditioner is 1,000 kg per mu, and the amount of bio-organic fertilizer is 100 kg per mu. After the two are evenly spr...

Embodiment 3

[0096] The 1st Company of Regiment 36, Milan Town, Ruoqiang County, Xinjiang improved saline-alkali land and planted 20 mu of ash jujube. The land belongs to desertified saline-alkali land. The saline-alkali land is not treated with soaking and salt washing, and the soil improvement and planting programs include: application of basal fertilizer, application of top-dressing fertilizer, and spraying of biological pesticides.

[0097] 1. Application of basal fertilizer

[0098] The dosage of soil conditioner is 1,500 kg per mu, and the amount of bio-organic fertilizer is 150 kg per mu. After evenly spreading the soil, 20 cm of soil is turned over, so that the two are fully mixed with the soil, and saplings are transplanted after 6 days.

[0099] Second, the application of top dressing

[0100] Fertilization method:

[0101] (1) After transplantation, apply compound amino acid biological liquid fertilizer, the dosage is 10 kg per mu, and slowly irrigate after diluting compound a...

Abstract

The invention discloses a method for soil improvement and crop planting in saline-alkali soil, and aims to improve the physical and chemical properties of the saline-alkali soil and the physiologicalmetabolic ability of crops planted in the saline-alkali soil. The method disclosed by the invention comprises the steps of applying base fertilizer, applying topdressing, and spraying biopesticide. Compared with the prior art, a soil conditioner, bio-organic fertilizer, compound amino acid biological liquid fertilizer, organic liquid fertilizer, Fuhuanong, and compound plant source nano-pesticideare adopted without consuming fresh water to leach and eliminate salt; environment-protection and pollution-free effects are achieved; three-dimensional fertilization and field management are realized; comprehensive soil improvement measures and planting are implemented; the physical and chemical properties of the saline-alkali soil are effectively improved; the salt tolerance and survival rate of the crops are improved, so that the crops can grow and develop healthily in the saline-alkali soil, thereby obtaining higher harvest, and ensuring the yield and quality; meanwhile, a good ecologicalenvironment for soil is created, and the method is suitable for different types of the saline-alkali soil including saline alkali soil in coastal areas and soda saline alkali soil on the plain in thenorthwest inland areas.

Description

technical field [0001] The invention relates to a method for soil improvement and crop planting, in particular to a method for improving saline-alkali land and crop planting. Background technique [0002] According to reports, the area of ​​saline-alkali land (saline-alkali soil) with farming value in my country is as much as 525 million mu, of which 200 million mu of saline-alkali land with agricultural prospects, accounting for about 10% of the total cultivated land, is mainly distributed in the northwest, northeast and eastern coastal areas. area. Saline-alkaline soil is a general term for saline soil and alkaline soil. Saline soil refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, and the soil with higher pH is alkaline. Most of the large-scale saline-alkali soils have a pH above 8. Due to the accumulation of a large amount of...
