To increase the purpose of production.
11. Using technology
(1) The release of the seed "eat heat" damage
When the rice seed temperature exceeds 40 °C for more than 12 hours, it is washed first with water, then soaked with 250mg/L liquid for 48 hours, and the liquid is used to submerge the seed. After cleaning the liquid, germination at 30 °C can partially relieve the "eat heat" damage.
(2) Cultivate strong seedlings
Wheat was soaked with 0.3%~0.5% liquid for 6 h, liquid: seed = 1:0.8, dried and sowed, seeded with 2%~3% liquid sprayed on the seeds, simmered for 12 h, but Miao Zhuang The root system is developed, the number of branches is increased, and the yield is increased by about 12%. In the initial stage of tillering, spray with 0.15 %~0.25% liquid medicine, spray liquid amount 50kg/667m2 (concentration should not be higher, otherwise it will delay heading and maturity), which can make wheat seedlings dwarf, increase tillering, increase yield by 6.7%~20.1% .
Corn is diluted with 50% water for 80~100 times soaking for 6h. The liquid is suitable for submerging the seeds. After sowing in the shade, the plants can be short, the roots are developed, the knots are low, no baldness, and the ears are full, and the yield is significantly increased. In the seedling stage, 0.2%~0.3% liquid medicine is used, and 50kg per 667m2 spray can play the role of seedling, and it is resistant to salt and alkali and drought, and the yield is increased by about 20%.
(3) inhibit stem and leaf growth, lodging resistance, increase yield
The spraying of chlormequat at the beginning of the tillering at the end of the tillering can effectively inhibit the elongation of the lower part of the stem from 1 to 3 knots, which is very beneficial to prevent wheat lodging and increase the rate of ear formation. For example, spraying 1 000~2 000mg/L of liquid medicine during jointing stage will also affect the normal development of the ear while inhibiting the elongation of the internode, resulting in reduced yield.
