Problems solved by technology

In nature, there is a single way for vegetables to obtain chitin, which can only be obtained by decomposing and absorbing chitin at the site of direct contact with insects, or obtaining chitin from insect remains decomposed by microorganisms in the soil, and fungal autolyzed bacteria.
However, with the extensive use of chemical fertilizers and pesticides in the farmland, the number of insects in the farmland has been greatly reduced, and the microbial ecological balance in the soil has been broken, resulting in varying degrees of chitin deficiency in the soil.
In addition, the promotion of greenhouse planting and soilless cultivation technology isolates insects from vegetables, cuts off the way for vegetables to obtain chitin, and leads to chitin deficiency.

Abstract

The invention discloses a method for using chitin to promote rooting of vegetable seedlings. The method is characterized by mainly including the following steps: 1), weighing, by weight, 5-10 parts of chitin powder, and preparing chitin organic water-soluble fertilizer with chitosan content to be 30-40g / l for standby use; 2), taking and diluting 50% of the chitin organic water-soluble fertilizer obtained in the step 1) by 700-800 times, and soaking roots of green vegetable seedlings in a dilution of the chitin organic water-soluble fertilizer for 0.3-1h; 3), subjecting the green vegetable seedlings to organic-ecotype soilless cultivation, and diluting another 50% of the chitin organic water-soluble fertilizer obtained in the step 1) by 500-700 times for sprinkle-applying when a leaf vegetable has 5-6 main leaves or a melon has 2-4 main leaves. By the method, the chitin is used to quickly increase rooting speed of the green vegetable seedlings, so that seedling recovery period is shortened; natural organic fertilizer is used in the whole process of planting, so that harvested vegetables are low in pesticide residue rate, and standards of green vegetables are met.

Description

technical field [0001] The invention relates to a method for promoting rooting of seedlings, in particular to a method for promoting rooting of green vegetable seedlings with chitin. Background technique [0002] Chitin, also known as chitin, chitin, chitin, clear cutin, polyacetylglucosamine, chemical name is β-(1,4)-2-acetylamino-2-deoxy-D-glucose, is a natural Polysaccharides are the only positively charged natural polymers in nature and belong to straight-chain amino polysaccharides. The molecular chemical structure of chitin is very similar to the cellulose widely found in plants. The hydroxyl group on the second carbon atom of the glucose molecule, a single molecule that makes up the cellulose, is replaced with an acetamido or amino group, so that the cellulose becomes chitin , Therefore, chitin can also be said to be animal fiber. Chitin widely exists in higher fungi, arthropod shrimp, crab, insect shells and other organisms in nature. Due to the strong hydrogen bo...
