How to use cotton seedlings
First, the use of cotton seedlings The cotton seedlings consist of three large, medium and small bags, the specific soaking steps are:
1. Soak 5 kg of cotton seeds with three open (about 70 °C) cold water for 5 minutes, remove the cotton seeds, and squeeze out the excess water.
2. Dissolve the pouch reagent in 0.5 kg of clear water, into the cotton soaked in three open and one clear water, stir while stirring, and leave it for 24 hours (intermediate stirring 2~3 times).
3. Dissolve the medium bag reagent in 1.54 kg of clean water, pour into the cotton seed soaked in the sachet reagent, and mix well for 24 hours.
4. Dissolve the large bag reagent in 1.5 kg of clean water, pour into the cotton seed soaked in the medium bag reagent, and mix thoroughly for 24 hours. After the treatment is completed, it can be sown, or placed in a wet bag to be germinated and then sown. When sowing the mountain merchants, the soaking time per bag can be shortened to 12 hours. Or soak 10 kg of cotton seeds with three open and one clear water, soak for 12 hours, remove the water control, dissolve the large, medium and small three bags of reagent with 2 kg of water, and then add the cotton soaked in three cold waters. The seeds were thoroughly stirred and left for 12 hours to carry out germination.
Second, matters needing attention
1. The process of cotton seedlings to treat cotton seeds is the process of cotton seed resistance exercise. The cotton seed is fully absorbed into the cotton seed, thereby reducing the intrusion of soil salt ions and pathogens, and improving the resistance of the cotton seedlings, and the effect is long. Shortening the soaking time or once soaking seeds is not as good as the time of soaking seeds for 24 hours.
2, when the cotton is desulfurized by sulfuric acid or when it needs to be broadcasted, it can be used without soaking the seeds and soaking seeds with cotton seedlings. However, the water content of the three bags of reagents was 1.8 kg, and the seeds were soaked in 6 kg. The other steps were the same.
3. When the cotton seedling-preventing agent and the pest control pesticide are used at the same time, after the seed soaking agent is used for three times soaking, the pesticide is mixed before sowing.
4, after soaking seeds with cotton seedling agent, if the cotton seed is not suitable for sowing, it can be blown a little for a while or for a while, but do not let the seeds lose too much water, otherwise it will affect the effect.
5. If the weather is dry during soaking, the seed loses water quickly, and the seed can be covered with a damp cloth; if the temperature is high (the average daily temperature is above 20 °C), the time for each soaking can be shortened appropriately to avoid the seed germination. Affect seeding.
