Abstract

The invention provides an improvement nutrient for saline and alkaline land. The nutrient prepared from biological bacteria, plant ash, Bacillus subtilis, kaolin, calcium carbonate and ardealite is scattered into the surface of the land and is characterized by being prepared from components by weight as follows: 20-24 parts of the biological bacteria, 26-30 parts of the plant ash, 5-10 parts of the Bacillus subtilis, 30-40 parts of the kaolin, 10-20 parts of the calcium carbonate, 20-30 parts of the ardealite and 60-70 parts of water. The improvement nutrient can well prevent nutrient substances from permeating underground layers, so that the saline and alkaline land can be improved more quickly within the effective time; meanwhile, the block structure of soil can be improved, the gas permeability of the soil can be better through cooperation of the nutrient and the ardealite, the concentration can be reduced to the extent suitable for plant growth within only one quarter, the plantlet survival rate in the first quarter is 99%, meanwhile, the cost can be reduced, moisture can be better preserved, and increase of the saline and alkaline degree is avoided.

Description

technical field [0001] The invention relates to a nutrient, in particular to a saline-alkali improved nutrient. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] The existing improvers can only slowly improve the salinity of saline-alkali land, and the water retention effect is not good, resulting in a poor improvement effect on saline-alkali land. Contents of the invention [0004] Aiming at the above problems in the prior ...
