      Water retaining agent

      2017-11-20 Writer:t349

      Since last winter and spring in most parts of the country the scarce precipitation, the emergence of a large range of drought and now spring corn is about sowing and increase Maize Germination rate is a key ring.

      How to improve the drought resistance and germination rate of Spring Maize in the arid soil. As we all know, the seed germination, the amount of water, if the soil moisture content is less than the required moisture content of the seed germination, it can not be normal germination or germination. Such as general seed, germination need to absorb the weight of the weight of the water to germinate, so to make the Spring Maize in the arid soil 20-30% normal germination, but also to sprout neat, no shortage of seedlings, drought and water retaining agent can play a certain role.

      Drought resistance and water use: 1 seed coating. For seed dressing: resistant to drought and water retaining agent three times diluted and added to the need, the coating of seeds, mix well after the heap stuffy 4-5 hours, no adhesion can sow seed. For soaking: put the seeds in drought resistance and water soaking in 12 hours after seeding, dry in the shade. The seedling root dipping. The seedling and seedling transplanting, the root of soil to root dipping, dip uniform after planting. The cuttings dipped in branches. The cutting branches in the branches, 4-5 cm basally, drought resistance and water dip, dip uniform planting. The spray. 20 grams per 500 grams of water and water for field spray, can reduce the evaporation of the leaves, improve the ability to resist drought, dry hot air.

      Used in corn or other seeds, mainly using the first technique.

      In the use of drought and water retaining agent, should pay attention to the following points:

      The drought insurance agent concentration can not be too low, generally 50 grams of drought insurance agent Duishui 100-150 grams, but the concentration is not too high, this will increase the cost.

      The water holding agent in water, in which the seeds need at least 5 hours or more stuffy, dried and sown to spread out.

      Seeds 2-3 after drought water retaining agent treatment within 3 days after sowing, or the seeds have moldy (in the high temperature days with particular attention to the possible, but will affect seed germination.

      How to Caution. Now most of the corn seed coating, coating is toxic, and drought resistant agent to increase the surface of the seed coat, and therefore must avoid contact with skin.

      . according to the author's many years of experience, drought insurance agent in use, whether it is dry or the rain is abundant, dressing, and wasn't rainy water mix sowing drought water retaining agent is harmful. But it is better to plant the rain, can absorb more moisture, when the drought and then release the water for crop growth needs. Some farmers believe that it is rainy, sowing and drought resistant agent is harmful, in fact, this is a wrong idea.
