Problems solved by technology

[0008] In view of the current advantages and disadvantages of acidification soil improvement methods at home and abroad, that is, the application of lime in traditional methods can easily lead to soil compaction and affect the soil micro-ecological environment, and the method of applying industrial by-products has high economic costs and environmental risks. Small, unclear ingredients and easy to cause non-point source pollution. The present invention proposes a method for progressive improvement of acidified soil and its planting synchronization using peptide calcium salts. According to the growth characteristics of plants, peptide calcium salts are used to The special biochemical characteristics, ecological characteristics and fertilizer efficiency characteristics of salt can realize the synchronization of acidified soil improvement and planting (crop seedlings can be transplanted at the same time or immediately after improvement), and overcome the shortcomings of existing improvement technologies, that is, it takes a period of time after improvement. The natural conversion and stabilization of time (3-20 months) can plant crops, affecting production efficiency

Embodiment 1

[0027] The strongly acidic (pH value 4.51) yellow clay farmland located in Enshi, Hubei was selected as the improvement base. The soil organic matter content was 9.57 g / kg, and the cation exchange capacity (CEC) was 12.05 cmol / kg. According to the alpine climate environment, it was suitable for local planting. The cruciferous crop cabbage (Jingfeng No. 1 spring and winter variety cultivated by the Vegetable and Flower Institute of the Chinese Academy of Agricultural Sciences). According to the method of the present invention, the application rate per mu is: 50 kg of peptide calcium salt, 10 kg of dipotassium hydrogen phosphate, and 1 kg of polyglutamic acid. On a sunny day, add 200 L of water to prepare on-site, stir evenly, spray on the soil and carry out simple The soil was turned and mixed, and the head cabbage seedlings with the same growth status were transplanted and planted to about 12 cm, and no fertilizer was applied during the growth of the head cabbage. Compared wit...

Embodiment 2

[0031] A moderately acidified (pH value of 5.32) yellow-brown loam farmland in Xinyang, Henan Province was selected for progressive improvement, and the Solanaceae crop pepper (Moxiu No. 8) was planted synchronously. According to the method of the present invention, the amount of application per mu is: 40 kg of peptide calcium salt, 8 kg of dipotassium hydrogen phosphate, and simply mix with the soil after directly spreading evenly on a sunny day, and then spray water until the soil is all moist (about 60% of the field water capacity). %-70%). Pepper seedlings with the same growth status were transplanted and cultivated to about 7 cm, and no fertilizer was applied during the growth of pepper. Peppers treated with peptide calcium salts were stronger and taller than those treated with compound fertilizers, and the fruiting period was longer. The total number of fruits (20.5) per plant of peppers treated with peptide calcium salts was more than that of the control (8.4) 12.1, th...

Abstract

The invention discloses a method for synchronizing progressive improvement and planting of acidified soil by using peptide calcium salt. The pH of the acidified soil is gradually increased for 2-4 times by using the peptide calcium salt, the pH of the soil is increased by 0.5-1.2 each time, crops are planted while the peptide calcium salt is used, the method can gradually improve the micro-ecological environment of the soil, acidified soil improvement and crop planting are carried out synchronously, and the defect that planting cannot be carried out in the existing acidified soil improvement process is overcome.

Description

technical field [0001] The invention belongs to the field of improvement mode and planting technology of acidified soil, and specifically relates to the new improvement mode, planting technical requirements, crop quality, yield and other directions and applications of fully water-soluble peptide calcium salt to acidified soil. More specifically, the present invention relates to A method for progressive improvement and planting synchronization of acidified soil by using peptide calcium salt. Background technique [0002] At present, the acidified soil area in my country has expanded to more than 40% of the country's cultivated land area, and the area of ​​strongly acidic soil (pH value <5.5) has increased from 169 million mu in the 1980s to 226 million mu. Acid gas (SO 2 , NO 2 etc.) and inappropriate application of fertilizers in agricultural production have exacerbated the process of soil acidification. Acidification activates the aluminum in the solid phase of the so...
