At present, it has entered the great heat, and cotton has also entered the peak of flowering and ringing. This period is the period of peak demand for fertilizer in the life of cotton. According to observations, most cotton fields have hit the top, with 12 to 14 fruit branches per plant. Since the cotton plants first need to ensure the water and fertilizer requirements of the bolls, the upper few fruit branches are in the most vulnerable position. There is almost no cotton field without fertilizer.
Don't be fooled by a seemingly sturdy cotton plant, thinking that there is no shortage of fertilizers. Be sure to look at the fertility performance of the top three fruit branches to determine if you need top dressing. The main manifestations of lack of fertilizer: the leaves become significantly smaller, the leaf color becomes lighter; the fruiting branches become significantly thinner; the bud color becomes lighter; the upper fruit branch only gives birth to 1 to 2 buds, not the third, the first bud and the second Bud size varies widely.
Urea has the highest nitrogen content (46%), and its fertilizer efficiency is relatively fast. It is a better choice for top dressing. General cotton fields in the first acres of topdressing 10 kg of urea should be based on acres of topdressing urea 5 kg, if the first time without urea or application of small quantities, the second to increase the amount. For reasons that cannot be used for soil dressing, foliar sprays should be applied immediately. Each mu should be sprayed with 2% urea solution 0.5 kg, sprayed once every 5 days, and sprayed 3 times.
Urea can be sprayed with pesticides and dildoamine, but it should be used immediately. Fertilizer can also be applied at the same time as the fertilizer is applied to the soil. This is a two-pronged approach because the cotton plant can no longer wait. If heavy rain falls, soil dressing and foliar spraying cannot be carried out, then urea can be sprinkled on the surface of the cotton in the rain. Although the fertilizer suffers some losses, it is much better than not chasing it.
