4 strokes of wheat in early spring
Scratch ploughing in the soil back to the top sparse Ling Ling, you can loosen soil, protect the earthworms, warming, weeding, and enhance the ability of wheat seedlings to keep out the cold. Regardless of weak seedlings, strong seedlings, or strong seedlings, they must pay close attention to cropping during the return period; for wheat fields with prosperous tendencies, they can also be properly squatted so as to restrain spring delivery. When ploughing, it is necessary to pay attention to grasping the shallow ridges and fine ridges, and push the rakes and rakes along the side while pushing; if the repression is carried out before the ploughing, the soil will not empty, and thus the effect of lifting the ridges and lifting the ridges will be received. In the early spring, the suppression of wheat field repression can crush the rubbish to close the cracks and make the roots of the wheat roots closely contact with the soil to prevent cold air from invading and damaging the wheat seedlings. At the same time, repression also has a lifting effect, which can increase the water content of the soil surface, which is conducive to alleviating cold and cold damage. Fertilization of wheat in early spring fertilization can make up for winter soil fertility, increase nutrient accumulation, promote the growth of young wheat seedlings, and resist or reduce early spring freezing injury. Especially in the winter, when the temperature is high, the seedlings continue to grow, and the soil consumption is high, early spring fertilization is particularly important. In early spring wheat fertilization, we should seize the favorable opportunity for the soil just thawed and returned to the slurry, by means of digging deep ditch; generally should not be watered, so as not to reduce the temperature, affecting the growth of wheat seedlings. Spraying the wheat in the green season, the spraying of 200ppm paclobutrazol solution per acre 30 to 40 kg, can inhibit the growth of wheat seedlings, enhance cold resistance.
