Sandy land soil conditioner capable of retaining water, fertilizing and inhibiting evaporation and application of sandy land soil conditioner

Номер: CN115926806A
Принадлежит:

The invention relates to a sand soil conditioner capable of retaining water, fertilizing and inhibiting evaporation and application, and belongs to the technical field of soil improvement. The sand soil conditioner capable of retaining water, fertilizing and inhibiting evaporation is prepared from the following components in parts by weight: 10 to 20 parts of improved pre-gelatinized corn starch, 15 to 30 parts of potassium polyacrylate, 30 to 90 parts of pure sheep manure organic fertilizer and 100 to 400 parts of fly ash. According to the sandy soil modifier, industrial waste is reasonably utilized again, harm is turned into benefit, waste is turned into wealth, the economic concept of recycling is met, and the problem that the environment is polluted due to waste accumulation is solved. The sandy soil modifier can effectively lock natural rainfall, effectively inhibit soil moisture evaporation, reduce irrigation cost, improve soil fertility and further improve crop yield in arid regions ...

Biological targeted regulating fertilizer as well as preparation method and application thereof

Номер: CN116640029A
Принадлежит:

The invention provides a biological targeted regulating fertilizer as well as a preparation method and application thereof, and relates to the technical field of biological fertilizers. The biological targeted regulating fertilizer is prepared from the following components in parts by mass: 26 to 78 parts of cow dung, 18 to 54 parts of sheep manure, 13 to 26 parts of bottom mud, 17 to 42 parts of water, 0.09 to 0.2 part of a microbial agent and 0.9 to 2.1 parts of hay. According to the biological targeted regulating fertilizer prepared from the components, recycling, productization and application of pollutants are realized, that is, the pollutants are changed into resources, and biological targeted regulating fertilizer products are produced and applied to grassland remediation to improve grassland soil nutrients, so that the grass yield of grassland is increased, and the vegetation coverage of the grassland is increased. After the problems of substandard lake water quality, difficulty ...
