Embodiment 1

[0013] Mix the following components according to the ratio: chitosan 10%, common soil 30%, humic acid 30%, attapulgite 15%, lumbrokinase stock solution 5%, citric acid 2%, superphosphate 3%, potassium sulfate 2 % and zinc sulfate 3%. Add 40 grams of seedling-strengthening agent per plastic tray, mix evenly, water to moisten, sow and cover with soil. Each pack of chitosan rice seedling soil is 10 kg, which can cultivate 120 trays of seedlings.

Embodiment 2

[0014] Embodiment 2 comparative experiment

[0015] The experiment was carried out at the experimental base of the National Japonica Rice Engineering Technology Research Center on March 5, 2016. Two factors were set up in the experiment, namely seedling soil treatment and seedling raising method. Seedling-raising is provided with two treatments of no seedling soil (control, conventional seedling raising) and seedling soil application (the amount of seedling soil is 40g / pan); each treatment is set to repeat 3 times, randomized block design, and the area of ​​the seedling field is 10m 2 . At the 3-leaf stage of the seedlings, samples were taken according to the relevant literature, and the plant height, stem base width, root number, and fullness of the seedlings were measured; the experimental data are shown in Table 1 respectively.

Abstract

The invention provides paddy rice seedling culture soil containing chitosan. The paddy rice seedling culture soil is prepared from the following components by mixing: 10 parts of the chitosan, 30 parts of common soil, 30 parts of humic acid, 15 parts of attapulgite, 5 parts of a lumbrokinase stock solution, 2 parts of citric acid, 3 parts of calcium superphosphate, 2 parts of potassium sulfate and 3 parts of zinc sulfate. The paddy rice seedling culture soil containing the chitosan, provided by the invention, contains a large quantity of organic matters, macroelements and microelements, can meet nutrients needed by growth and development of paddy rice seedlings and has the effects of improving the quality of the seedlings and improving disease and insect resisting capabilities.

Description

technical field [0001] The invention belongs to biological utilization technology, and in particular relates to rice seedling raising soil containing chitosan. Background technique [0002] The invention relates to a rice seedling raising soil containing chitosan. It solves the problems that currently used paddy seedling soil has low nutrient element content, large amount per unit area, high production and transportation costs, high fertilization labor intensity, cumbersome fertilization process, labor and time-consuming. [0003] Chitosan is a natural polymer compound with excellent properties such as biological functionality and compatibility, blood compatibility, safety, and microbial degradation, and has been widely concerned by various industries. It is widely used in medicine, food, chemical industry, cosmetics, etc. Significant progress has been made in applied research in many fields, such as water treatment, metal extraction and recovery, biochemical and biomedical...
