Embodiment 1

[0014] Embodiment 1 The composition containing chitosan oligosaccharide and glycine is to the effect of Dutch pea

[0015] Use sterilized soil and sterilized river sand to mix into culture soil, mix it into the composition or a single dose (the dose is calculated in milligrams of the medicament contained in each kilogram of soil) and mix thoroughly, add clear water to make the water content 30%, and fill it quantitatively. Put the soaked pea seeds into the pots, plant 10 seeds in each pot, cover with a thin layer of soil, set 4 repetitions for each concentration, and place them in an observation room (23-25° C.) for cultivation. After emergence, 5 seedlings of the same size were kept in each pot, and the average plant height and fresh weight of snow peas without roots were investigated and recorded 25 days after emergence. Move the remaining pot of each treatment to the light incubator (10°C) for 7 days and then place it in the observation room (23-25°C) to observe the growth ...

Embodiment 2

[0020] Example 2 The growth-promoting effect of the composition containing chitosan oligosaccharide and amino acid on corn

[0021] Use sterilized soil and sterilized river sand to mix into culture soil, mix in a certain amount of composition, mix well, add water to make the water content 30%, put it into the pot quantitatively, and plant the soaked corn seeds in the pot 15 grains in each pot, covered with a thin layer of soil, 3 repetitions for each concentration, placed in an observation room (23-25°C) for cultivation, and kept under the same light, temperature and watering management. After emergence, keep 10 seedlings of the same size in each pot, spray once after 10 days, and spray once every 10 days, for a total of 2 sprays. The average plant height of each pot of corn was recorded when there was a significant difference between the treated and control plants.

Embodiment 3

[0026] Example 3 The yield-increasing effect of the composition containing oligochitosaccharides and glycine on rapeseed

[0027] Apply enough base fertilizer to the experimental field and divide it into small plots, put on a sign, and make it level and even. 10m per community 2 1. Wet the rape seedbed with the same amount of tap water in each plot to avoid damage to the roots of the seedlings. The transplanting density should be 100 plants per plot. At the three-leaf stage, pre-flowering stage, and young fruit stage, the corresponding pesticides were used for targeted root irrigation treatment once on the same day, and the root application rate and concentration of each plot were the same. Harvest when 2 / 3 siliques are yellow-green and the central part of the main shaft is loquat-colored, and weigh the rapeseeds in different plots. During this period, other management measures in each plot were the same, such as water, weeding and so on. The yield results are shown in Tabl...

Abstract

The invention belongs to the field of agriculture and relates to a synergistic composition containing chitosan oligosaccharide and amino acid. The composition contains the following active substances in percentage by mass: 0.1%-3% of chitosan oligosaccharide, 0.2%-50% of amino acid and 0.1%-20% of an element fertilizer, wherein the element fertilizer is one or more of molybdenum, manganese, zinc, copper and iron and is added in a form of soluble salt; and the mass percent of an assistant component is 20%-90%. The composition is mixed with soil or / or mixing seeds when in use, or / and the composition is used in a spraying or / and root-irrigation manner in a plant growing period; and the application concentration of the composition is 2-100mg / Kg or mu g / g. The composition provided by the invention has obvious growth promotion, yield increase, stress tolerance, flower retention and fruit retention effects on plants.

Description

technical field [0001] The invention belongs to the field of agriculture and relates to a composition, in particular to a synergistic composition containing chitosan oligosaccharide and amino acid. Background technique [0002] With the continuous improvement of people's living standards, green agricultural products are becoming more and more popular. Due to the change of soil pH and the decline of product quality caused by long-term and large-scale application of traditional fertilizers, it is imminent to develop a formulation that is friendly to the environment, promotes growth, and increases crop yield. [0003] Oligochitosan is made by depolymerization of chitosan. It is an upgraded product of chitin and chitosan, and has incomparable advantages of chitosan. It has the advantages of low molecular weight, good water solubility, great function, easy absorption by plants, and high biological activity. As the smallest molecule of protein, amino acid has the characteristics...
