Seed germination accelerating agent capable of improving drought resistance

Abstract

The invention discloses a seed germination accelerating agent capable of improving drought resistance. The seed germination accelerating agent is prepared from the following raw materials in parts by weight: 6-8 parts of shrimp shell meal, 15-19 parts of cassava residues, 6-7 parts of maple syrup, 3-4 parts of calcium nitrate, 9-11 parts of ammonium bicarbonate, 3-4 parts of chitosan, 52-54 parts of fresh ageratina adenophora, 23-26 parts of fresh oysters, 0.6-0.8 part of a pseudomonas aeruginosa bacterium agent, 1.4-1.6 parts of a high-temperature cellulose-decomposing bacteria bacterium agent, proper amount of 6mol / L hydrochloric acid solution and proper amount of water. According to the germination accelerating agent, organic and inorganic matters are compounded and are cooperated with natural macromolecular substances including the chitosan and the like; the activity of seed enzymes can be effectively improved when seed coat surfaces absorb the germination accelerating agent; and peroxidation of celluloses is reduced and the synthesis of protein and mRNA in the seeds are improved, so that the germination rate of the seeds is wholly improved, the inhibition on internal physiological activity of the seeds by a drought condition is relieved and the germination quality of the seeds is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural accelerating germination, in particular to a seed accelerating agent for improving drought stress resistance. Background technique [0002] With the development of agriculture, the rapid growth of seedlings has become an important measure to increase the yield of agricultural, forestry and animal husbandry economic crops. However, due to unsuitable external environment or immature growth of seeds, the seeds have long dormant period, low germination rate and irregular germination. And the low quality of germination seriously affects the growth of later crops, and causes a series of problems such as long production cycle and low product quality, which affects economic benefits. The germination agent can effectively solve the above problems, but the current germination technology mostly uses plant growth regulators for germination. The waste of resources and the unsatisfactory specific use effe...
