Cotton enters the flowering period from early July, and the time to boll during the end of August and early September is the flowering and boll period. The flowering and boll period is the most vigorous period of cotton growth and development, and also a key period for determining yield. In this period, it is necessary to strengthen the management of fertilizer and water and apply the flower and bell fertilizer, which is an effective measure to increase cotton production. For cotton fields with early flowering and severe drought, it is necessary to combine the watering and applying the flower and bell fertilizer. Flower bell fertilizer should be applied early and reapplied. According to soil fertility and cotton growth, urea, phosphorus and potassium fertilizers should be topdressed as appropriate. Combined with spraying cotton Zhuangting, it can increase the absorption and absorption of plants, increase the vitality of cotton buds, and protect the buds. Baoling, Baotao.
The flowering and bolling period needs to be controlled in time to shift the growing nutrients more to reproductive growth and reduce the bud bells. Spraying the Huawang 3 cotton topping agent can force the top of the cotton to return to the development of the cotton peach, weakening the top advantage until the top Stop growing. It can effectively improve the canopy permeability of the cotton field, prevent premature aging, increase the effective boll weight and increase the yield. For cotton fields that bloom too early, combined with pruning, the early flowers and young bells before July 5th can be removed, which is good for preventing premature aging and preventing rotten bells.
The diseases that are prone to occur in cotton flowering and bolling stage are mainly verticillium wilt, blight, ring rot, red leaf stem blight, and squamous blight. Field management should be timely sprayed with targeted chemical control according to the law of disease occurrence, which can be combined with tree protection. The generals use it in combination to quench the virus in the germination stage, enhance plant resistance and immune positive energy, and protect its healthy growth.
