Texas: Summer corn has entered the pest during grouting period, anti -disaster and mitigation, anti -falling, premature aging, and premature aging is the key

At present, the summer corn in Texas has entered the grouting period, which is a critical period to determine the weight. The main goal of field management is premature aging, large ears, and granularity weight. The main task is to prevent diseases and insects, prevent disaster and mitigation, prevent falling, and prevent premature aging. Harvest and rear damage.

Summer corn is generally sowed with fertilizer. Due to the large precipitation, strong intensity in the early stage, and growing rapidly, soil nutrients, especially nitrogen, are severely losing, and can easily cause fertilizer. At this time, we should pursue it reasonably to promote the grouting of the grains.

Water water in time to maintain reasonable feelings. To maintain the appropriate soil in the corn flower period, if there is waterlogging in the field, the soil humidity is too large, which will affect the breathing of the root system, reduce the photosynthesis, and affect the output. In order to prevent excessive rainfall, the ditch should be dredged as soon as possible, especially the water drainage system is improved to ensure that the water accumulation is discharged in time. For low -lying plots that have accumulated water, mechanical drainage should be used to reduce corn flooding time. At the same time, it is necessary to pay attention to the rapid turn of the drought and flood to prevent droughts affecting the grain grouting during the grouting period. It should not be irrigated too much in the later stage of grouting to prevent greedy late maturity and affecting seeds dehydration.

Control the rule and prevent good diseases. While doing normal and small spot disease, top corruption, ears rot, corn crickets, cotton bells, peach crickets, and other routine diseases and insect pests, pay special attention to major pests such as southern rust, grassland greedy moths, sticky insects and other pests. The prevention and control of and actively promoted the integration of specialized control and green prevention and control, and reduced production losses caused by diseases and insect harm.

Texas corn is generally in the early stage of grouting, and the number of ears and ears of ears and grains have been formed. Later, it is a critical period to determine the weight of the granules. After the formation of the grains, the upper leaves of the plant can maintain strong light synthesis to prevent the leaf cutting from the top. Spray the leaf surface fertilizer, slow down the aging process of the plant, and strive to achieve high yield and efficiency of high yield and efficiency; in addition, most varieties of fertility will be long, and it cannot be fully mature during harvest. Harvest can extend the time of grouting, increase the accumulation of dry substances, give full play to the high -yield potential of varieties, and realize the harvest in the warehouse.
