1. Dry seeds and seeds, the first seed after the seepage. According to the principle of unreasonable time, the cotton fields without seep water can be dried seeds or soaked for 2 hours to 3 hours, then the seeds can be sowed out after sowing and sowing. When there is electricity, they can seep through quickly to ensure emergence. 2. Ditch water seepage, gutters seepage. In order to save water and electricity, open a ditch in the absence of electricity, make a good job, and immediately infiltrate the water when electricity is available to maximize efficiency. 3. Ditch digging nests and carry water. The farmers with small area of ​​cotton planting or dryland cotton fields can adopt the method of digging or digging water to seep into the soil, and then plant seed by means of seeding. But must deal with cottonseed, the method is: Use three open to a cool warm water (55 °C ~ 60X2, 1.5 times the seed weight) soak seeds for half an hour, the use of water heat sterilization, after half an hour then add cold water soak 8 hours ~12 hours, fully absorb the water, remove and control dry, mix the seed with 1% of Baomiao Ling and mix the sand and mix well. 4. Prolong the sowing period and increase the density. For cotton fields that cannot be planted in real time, they can be planted in the middle or late April when rain or water is available, but no later than May 5. Can take a boring germination approach to shorten the emergence time. The method is: pour the seeds on the ground, spray the seeds into the sprayer with water of 25°C-30°C, and continue to stir until sprayed until the water does not flow. Then cover it with a plastic film, spray water for 5 hours to 6 hours until it gets soaked, and then cover the hole for 24 hours until most of the seeds are slightly exposed white buds. When boring germination, in case of weather changes can not be timely sowing, ventilation should be promptly stalled to delay the germination process, can still be used after fine weather. However, it is necessary to increase the amount of sowing and increase the density of seedlings. The density of late-seeding cotton fields should reach 8,000 per mu, relying on groups to win high yields and high quality.
