During the late and middle stages of the elongation, the sugarcane is tall and has many leaves. If it is hit by wind and rain, it is easy to fall down. Especially after the rain, the water surface of the tail of the sugarcane plant becomes too heavy, and it will fall down when a wind blows. After sugar cane lodging, the segment near the ground tends to grow long roots, draw side buds, change cane stems, consume nutrient between the shoots, cause hollow or Puxin, reduce sugarcane yield, reduce sugar content, and produce bad ratoon cane. In the cane fields and high-yield sugarcane fields with frequent winds from July to September, lodging is the key to seizing high yields of sugarcane. The following five measures are taken to prevent lodging of sugar cane:
First, choose anti-wind and lodging-resistant varieties. Resistance to lodging is characterized by the firmness of cane stalks, stout basal, upright growth, late growth, but not conducive to lodging.
Second, apply base fertilizer. Sugar cane should be applied to base fertilizer, apply topdressing as early as possible, reasonably apply N, P and K fertilizers without applying partial nitrogen fertilizer, so that the sugarcane seedling stage is robust, the sugarcane plant is not long and the lodging resistance is improved.
Third, deep shallow ditch, high earth. The roots of sugar cane grow from the roots of the roots of the cane stalk. The high earth can increase the root zone of the roots, increase the length of the cane, deepen the roots of the cane, stabilize it, strengthen the wind resistance, and prevent lodging. If the planting ditch is too shallow, it can easily cause lodging.
Fourth, stripping leaves lodging. The lower part of the sugar cane has dried up, and the old leaves have low photosynthetic efficiency. In the later stage of sugarcane, only 6-7 leaves of the whole leaf can be kept, and the excess old leaves and dead leaves should be stripped to reduce the weight of the cane stalk and reduce it. Affect the wind area to prevent lodging.
V. Zha can prevent lodging. Sugarcane plants are tall. When the sugarcane plant reaches a height of 2 meters in September, the two rows of cane are bundled into a “human†shape, which can effectively prevent lodging.
Innovative jet embedded nylon technology maximizes the efficiency of sample collection from patients. Nylon adheres vertically and evenly to the surface of the swab tip, improving the efficiency of cell and liquid sample collection and release. Increased analytical sensitivity, no specimen residue, and accelerated specimen processing.
