Nutrient solution used for seedling rejuvenation

Abstract

The invention discloses a nutrient solution used for seedling rejuvenation. The nutrient solution is prepared from the following raw materials in parts by weight: 40 to 50 parts of wheat bran, 6 to 8 parts of nanometer carbon, 6 to 9 parts of ammonium sulfate nitrate, 1.1 to 1.3 parts of alpha amylase, 12 to 15 parts of water glass, 30 to 34 parts of fulvic acid, 1 to 2 parts of an indolebutyric acid preparation, 140 to 150 parts of rice bran, 2 to 4 parts of ethylene diamine tetraacetic acid disodium salt, 90 to 100 parts of fed maggots, 0.8 to 1.0 part of trypsin and a proper amount of water. By using the nutrient solution provided by the invention to spray seedlings, the survival rate of transplanting of the seedlings, especially ancient trees, can be significantly improved; meanwhile, the nutrient solution contains a plurality of nutrient substances needed by the seedlings, so the requirements of all tree varieties in different stages for nutrition can be met; and the nutrient solution is combined with actions of a variety of enzymes and complexing action through a multi-step process, so easy absorptivity of the nutrient solution is greatly improved, and good rejuvenation effect is exerted on the seedlings which are malnourished and grows weakly.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient solution for seedling rejuvenation. Background technique [0002] Nutrient solution is a functional liquid with less impurities and multiple nutrients. It plays an important role in plant nutrition supplement and soilless cultivation. Because of its high nutrient content and low dosage, it is widely used in daily life and agricultural production. There are tons of uses. At present, the preparation method of nutrient solution on the market is to mix various inorganic quick-acting water-soluble nutrients, add water to dissolve and dilute, and the plant nutrient solution obtained in this way has obvious defects in nutritional balance and absorption utilization rate. [0003] With the gradual acceleration of urban afforestation, a large number of seedlings need to be transplanted, and the unearthed trees do not have enough nutrients to supplement, and are easy to suff...

Problems solved by technology

[0003] With the gradual acceleration of urban afforestation, a large number of seedlings need to be transplanted, and the unearthed trees do not have enough nutrients to supplement, and are easy to suffer from diseases and weaken. However, there is no better nutrient solution on the market for the rejuvenation of seedlings transplanted. prepare
