Embodiment 1

[0014] Embodiment 1 contains the effect of the composition of humic acid and chitosan or chitosan on the growth of wheat

[0015] Divide the field into different plots, each plot is 30m 2 , Different plots are sprayed with different compositions or 2000g of a single dose of liquid medicine, and then after deep plowing, 650g of wheat seeds are sown in each plot and raked evenly. 20d post-emergence and tillering stage were treated with the corresponding pesticides and sprayed once in the corresponding plots at the conventional dosage. Observe the growth of wheat, see Table 1 for details.

[0016] The effect of table 1 composition on wheat growth

[0017]

[0018]

[0019] Table Note: In the table, "-" means "average", "+" means "good", and "++" means "better".

[0020] As can be seen from Table 1, the composition has an obvious promoting effect on the growth regulation of wheat (see Table 1), and when the active component in the composition was 1:3 and 3:1 when the rati...

Embodiment 2

[0021] Example 2 The effect of the composition containing humic acid and oligochitosan or chitosan on rice diseases in heavy metal polluted areas

[0022] According to the plan, compound preparations and single-dose preparations were prepared, and the activity pre-test was carried out with heavy metal-contaminated soil in the sewage discharge area of ​​mining enterprises. According to the pre-test of activity determination, the preparation is formulated into the required concentration. Dress rice seeds with chemicals (concentration is measured in effective milligrams of chemicals per kilogram of seeds), and select the farmland around the mine for sowing and raising seedlings. The investigation starts before the seedlings are transplanted, and each treatment is sampled at five points, 100 plants per point, and the diseased plant rates of plant rot, blight, and bakanae disease are counted, and the above-mentioned 1-3 diseases are counted as one plant. calculate. During plant g...

Embodiment 3

[0029] Embodiment 3 The composition containing humic acid and oligochitosan or chitosan affects the growth of cotton in saline-alkali soil

[0030] Select fields with relatively large salinity and alkali content (soil pH is 7.8-8.0), uniformly apply fertilizer and spray water to maintain a certain humidity before finishing the plots, and then arrange the plots evenly, dig holes and sow at intervals of 0.4m×0.3m, and sow in each hole Two germinated seeds were sown at the same depth, covered with thin soil, and sprayed with water quantitatively to promote seedling emergence. 7 days after emergence, keep 1 plant with the same growth in each hole, apply 100mL of the pesticide within the diameter of the root of the plant within 15cm of the measuring cup for each treatment, and apply the same pesticide and the same amount of pesticide once every 15 days, a total of 3 times. 45 days after sowing, the plant height and the number of buds of each cotton treatment were investigated, and ...

Abstract

The invention belongs to the field of agricultural products, and relates to a composition containing humic acid and chitosan oligosaccharide / chitosan, and application thereof to growth regulation and disease prevention. In the composition, the weight ratio of humic acid to chitosan oligosaccharide / chitosan is 1:10-10:1, plants are processed by employing the composition for performing at least one pesticide application manner such as spraying, seed dressing, irrigation at root, the composition with the concentration same to or different from that of the first applied composition is applied for 0-3 times every other 10-20 d, and the application dosage of the composition is 5-100 ppm, and the composition is capable of improving the effects of promoting crop growth and preventing diseases.

Description

technical field [0001] The invention belongs to the field of agricultural products, in particular to a composition containing humic acid and chitosan or chitosan and its application in growth regulation and disease prevention. Background technique [0002] Domestic saline-alkali soil has a wide distribution range and a large area. Due to the destruction of mineral resources, excessive use of agricultural materials, sewage irrigation, etc., the soil structure and quality have been seriously damaged and heavy metal pollution, and the yield and quality of food, fruits, vegetables and other crops have decreased. As people pay attention to the quality of agricultural products and the ecological environment, the research on soil improvers and non-toxic and residue-free agricultural products has become one of the hot spots of research and development workers. [0003] Humic acid is a kind of natural organic weak acid, which is composed of three parts: fulvic acid, black humic acid...
