Generally speaking, the period of seed harvest is solved in high temperature and high humidity, so in this period, how to create good storage conditions, is an important premise to maintain the laboratory low temperature cabinet and prolong the germination rate of seeds, especially the current development of agriculture for seed quality ultra-low temperature cabinet requirements are increasingly high. Therefore, in the practical work, giving full play to the advantages of low temperature and low humidity storage cabinets for seeds is very important to do a good job in seed storage, which is helpful to obtain good economic and social benefits.
By comparing storage at normal temperature with storage in low temperature and low humidity cabinet for seeds, we can find that the application effect of low temperature and low humidity cabinet for seeds is very obvious, and its advantages are mainly concentrated in the following aspects:
1. The low temperature and low humidity environment created by the low temperature and low humidity storage cabinet can maintain and stabilize the germination rate of seeds
Low temperature and low humidity storage cabinet can make the temperature in the cabinet professional production of low temperature cabinet to keep below 14℃, relative humidity between 60-65%; In normal temperature storage, the room temperature in summer is usually between 29-31℃ and the relative humidity is 70-80%. Therefore, seeds in the seed low temperature and low humidity storage cabinet over the summer, can not be affected by the high temperature and high humidity environment, seed respiration weakened, physiological metabolism is slow, seed viability has been naturally prolonged.
2. Seeds have fewer pests
Low temperature and low humidity storage cabinet of seeds, low temperature and low humidity, such an environment is not conducive to the growth and activity of pests, so the use of low temperature and low humidity storage cabinet seed storage, obviously will feel less seed pests, so as to ensure the quality of seeds, improve the germination rate of seeds.
3. Save seeds
The research showed that the use of low temperature and low humidity storage tank to store seeds for one year increased the germination rate of seeds by 10-30% compared with that of normal temperature storage, which could save a lot of seeds and avoid resource waste.
4. Reduce costs and increase benefits
Using low temperature and humidity storage tank storage seed, can not only reduce the cost of normal temperature library fumigation medicine, also can reduce the harmful gas of adverse effects on the seed, and to regulate the contradiction of seed years we also have obvious effect, to ensure the crop JiJue timely is being supported kind, stable prices for seeds, reduce the burden of the peasants, which reduce the cost of seed storage, It adds to the benefits.
