Embodiment 1

[0018] Soaking seeds with nano-chitin aqueous suspension can promote the growth of wheat roots and seedlings. However, different treatment concentrations had different effects on wheat growth. As can be seen from the table below, with the soaking time of 30s, as the concentration of nano-chitin increases, the roots and stem nodes of the seedlings grow faster. When the soaking time exceeds 30s, 0.003% nano-chitin can significantly promote the growth of roots and stem nodes, while high-concentration nano-chitin can mimic the growth of seedlings. According to comprehensive data analysis, soaking seeds with 0.003% nano-chitin for 10 minutes, the roots and stems of seedlings grow the fastest, which is the best condition for soaking seeds.

Embodiment 2

[0022] Applying nano-chitin aqueous suspension to roots of wheat seedlings before the greening stage can improve tillering. Different concentrations of nano-chitin can improve the tillering amount of wheat to varying degrees. According to experiments, applying 0.001%-0.005% nano-chitin to the roots of wheat seedlings before the greening stage can increase the tillering by more than 10%.

Embodiment 3

[0025] Under natural conditions, different concentrations of nano-chitin suspensions were used to root-apply wheat at the seedling stage, and it was managed and topdressed according to normal wheat growth until harvest. After the test, after jointing of wheat, the number of tillers was obviously more than that of the control, and the growth was vigorous, the stalks were thick, and the plant height increased. After booting, the ear length and grain number increased significantly. After the wheat was harvested, the number of grains per ear, seed setting rate, thousand-grain weight and yield were tested and analyzed. 0.005% nano-chitin can increase the yield by more than 20%. In the table below, different letters in the same column indicate a significant difference at a 5% level; the significant level refers to the comparison between different treatments of the same wheat variety, and no comparison between varieties is made.

Abstract

The invention discloses application of chitin to promoting production of wheat. The application has the advantages that at first, nanometer chitin preparation-water suspension is an environment-friendly preparation without any organic or inorganic additive; secondly, the nanometer chitin preparation is applied to crops with the ultra-low dosage, both yield and income can be increased, and pollution to water and soil and environment caused by application of agricultural chemicals can be reduced; thirdly, agricultural wastes are mainly adopted to produce a nanometer material, cyclic utilization of agricultural waste resources can be promoted, and the ecological environment can be improved; fourthly, the technical requirement for users is not high, work, time and labor can be saved, and the application meets the economic reality of the current rural society.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to the application of chitin for promoting wheat production. Background technique [0002] At present, chemical preparations and products are still the main means of agricultural production in my country. The extensive use of chemical preparations, pesticides, and chemical fertilizers has caused major social problems such as increased resistance to diseases and insect pests, soil degradation, environmental pollution, and excessive pesticide residues in agricultural products. In good health. In recent years, not only has the price of agricultural production materials soared in my country, but also the shortage of labor force and the sharp increase in wages of agricultural workers have forced agricultural production to urgently need light and simple technology. Fertilizer is not only an important means of agricultural production, but also traditional agricultural fertiliza...
