Nutrient solution for preventing frost damage of plant and production method

Abstract

The invention relates to a plant freezing injury resistant nutrient solution containing potassium hydroxide hydrolysate of plant seed dregs and peat, phosphoric acid, a microelement fertilizer and polyatomic alcohol and a preparation method thereof. The nutrient solution has the functions of promoting photosynthesis of plants, reducing the moisture in plant cells, preventing membrane lipid from being converted from liquid to gel at low temperature, has the advantages of reasonable formulation, low energy consumption in production, simple and convenient production technique, convenient use, increase of the crop output, reduction of the labor intensity, and the like, and has wide application in the fields of agriculture, forestry and the like.

Description

technical field [0001] The invention relates to a plant antifreeze agent, in particular to a plant antifreeze damage nutrient solution and a manufacturing method that enable plants to grow normally at a relatively low temperature. Background technique [0002] Generally, plants cannot grow normally in low temperature seasons, such as late autumn, winter, and early spring, due to the sharp drop in external air temperature. In order to enable plants to grow normally, people adopt measures such as greenhouses and plastic greenhouses; in order to obtain a good harvest, there are still measures such as setting air conditioners in the greenhouses and heating in plastic greenhouses. Generally, in order to save costs and maintain the temperature in the plastic greenhouse to facilitate the growth of plants, it is also necessary to build a small arch in the plastic greenhouse and add shed covers outside the plastic greenhouse. Although the above measures have been taken, there are st...

Problems solved by technology

Although the above measures have been taken, there are still reasons for the large cooling range and long cooling time of the cold air, which cause freezing damage to the flowers, tree buds, leaves, and fruits of the plants, and even the whole plant is frozen to death.

[0003] The fruit trees cultivated in the open air will also be damaged by freezing due to the large cooling range and long cooling time of the cold air, so that the flower buds are frozen and cannot bloom, and sometimes even the whole fruit tree is frozen to death and suffers heavy losses.

[0004] In view of the above deficiencies, the present inventors have studied for a long time and found that when freezing damage occurs, the water content in the plant cells is affected by the cytoplasm and the cell membrane and cannot be discharged freely, and there is freezing in the cells, which causes the cell volume to expand. The cell wall ruptures, causing carbohydrates, soluble amino acids, DNA, organic potassium, sugar and other substances that maintain cell vitality to flow out; this affects the stability of the biomembrane, and the membrane lipid also changes from a liquid state to a gel state, and the cell membrane cracks. eventually cause the plants to freeze and die
