Problems solved by technology

[0002] As we all know, with the rapid development of production technology and rapid population growth, people's desire to increase land production is becoming increasingly urgent. The use of a large amount of chemical fertilizers and pesticides is very harmful to soil and crops, and pollutes the environment on which people live. , and endanger people's health. Modern scientific research shows that the growth of plants not only needs ordinary nitrogen, phosphorus, and potassium fertilizers, but also requires essential trace elements, compound amino acids and a certain amount of plant growth promoters. The existing various plant growth promoters cannot Maximize the best effect of promoting plant growth, the use of plant varieties is small, and the effect of increasing production is unstable

Embodiment 1

[0030] Embodiment 1 Composite oligosaccharide plant growth promoter affects lettuce growth and yield

[0031] The compound oligosaccharide plant growth promoter is prepared into a solution according to the ratio of 10 grams plus 20 kilograms of water and 10 grams plus 30 kilograms of water, and a control experiment is carried out with clear water respectively, soaking the lettuce seeds for three hours, and sowing in early September. On the 4th day, the 8th day, and the 11th day, samples were taken from 20 plants to investigate the largest root and the largest root transverse stem of the plant respectively, and the rooting test was carried out.

[0032] Spray the lettuce with the aqueous solution (containing clear water control) that has been prepared with the above-mentioned accelerator, spray when the seedlings grow to 5 leaves, spray once every 7 days, and treat the whole growth cycle with the accelerator 3 times.

[0033] The germination rate of lettuce seeds is significant...

Embodiment 2

[0044] Embodiment 2 Composite oligosaccharide plant growth promoter affects lettuce growth and yield

[0045] Guangyan No.3 was used as the test cucumber

[0046] The compound oligosaccharide plant growth promoter was formulated into a solution according to the ratio of 10 grams plus 20 kilograms of water and 10 grams plus 30 kilograms of water, and a control experiment was carried out with clear water respectively. The cucumber seeds were soaked for three hours, and the seeds were sown in early September. On the 3rd day, 6th day and 9th day, 20 sheep were taken respectively to investigate the largest root and the largest root transverse stem of the plant, and carry out the rooting test.

[0047] Sowing was carried out in September, 2007, and the growth promotion test was carried out. Three groups and three repetitions were established, with a total of 18 districts, each with an area of ​​20 square meters. The experimental results are as follows:

Abstract

The invention relates to a composite oligosaccharide plant growth stimulator and a preparation method thereof, wherein the composite oligosaccharide plant growth stimulator comprises the following components and contents (calculated by weight percent): 1-5% of oligomerization chitosan, 1-5% of fructo oligosaccharide, 1-2% of oligomerization glucan, 10% of beer yeast hydrolysate, 0.5-1% of trace element, 10% of KH2PO4 and the balance of chicken manure water extract, which add up to 100%. The preparation method comprises the steps of: (1) preparing beer yeast hydrolysate; and (2) mixing the beer yeast hydrolysate obtained in the step (1) with oligomerization chitosan, fructo oligosaccharide, oligomerization glucan, trace element, KH2PO4 and chicken manure water extract according to the ratio, and obtaining the composite oligosaccharide plant growth stimulator. The invention is non-toxic, harmless and environmental friendly, can stimulate the growth and prematurity of plants, improve the yield, can improve the stress resistance of the plants and the quality of medicinal materials, and has wide application scope.

Description
