Due to the significant postponement of the sowing period, coupled with the continued low temperature and low rainfall, Xinghua City has a slower transformation of wheat in field crops, with large imbalances between plots and complex seedlings. At present, all fields should be carried out in time for four tasks, namely, trenching, trenching, seedling classification, supplementation with seedlings, promotion and control, and classification management for different estuaries, sowing dates, sowing rates, and sowing methods.
Attaching great importance to the flooding of the ditch construction is the most important obstacle to the growth of wheat. It is necessary to surprisely use the winter leisure to do a good job of internal and external “three ditch†reprocessing, so that the canopy can be discharged, the drought can be filled, and the rain can be stopped.
Drought and water dominated the field of anti-freezing This year, early drought sowing of buckwheat sows, sowing, the current group is too large, group and individual quality generally poor, with the accelerated birth process after the spring, the risk of freezing damage, will increase the lodging. For drought-wheated wheat fields with too much seeding capacity, one must make surprise checks on seedlings and seedlings. Artificial seedlings can be used to raise the seedlings to reduce the density. Secondly, water and fertilizer must be controlled to reduce ineffective deliveries. The plots of excessively prosperous wheat seedlings should be suppressed and controlled, and fine weather should be selected to suppress the cracks at the right time. The control should promote the crushed soil blocks and bridge the earth seams to enhance the cold resistance of the plants. The weight of the cement mortar or stone mortar used for repression shall be controlled between 100 and 150 kilograms, or it shall be stamped by hand, and the wheat field may be repressed twice. The wheat seedlings cannot be suppressed after jointing. In the sunny days, the dew is dry and suppressed, and the rainy days and the dew cannot be repressed when the dew is dry. The wheat fields cannot be repressed when they are too wet. The winter and spring soils and wheat leaves cannot be repressed when they are not thawed.
Late seeding of rice and barley is sufficient for fertilizer supplementation. For the current field where the number of stems is still not enough seedlings, the seedlings should be quickly applied once, and 6 to 8 kg of urea per mu should be applied to promote the transformation of weak seedlings. If there is still no rainfall in the near future, it is necessary to make up for fertilizer in a timely manner.
Appropriate broadcast enough for Miaotian and late sowing
For the more than 350,000 stalks per acre or the basic seedlings per acre in the 260,000 to 300,000 late sowing field, should control the late application of wax fertilizer and return green manure. The wheat fields planted on a proper date will be controlled under 800,000 per acre peak population; the seedling and ear ratio will be 0.7 to 1:1 in late sowing stalks to cultivate wheat fields, and the peak seedlings per acre will be controlled under 850,000.
The single-rooted seedlings sown late must be swiftly promoted, so that early-stage births can be planted late in late November to early December. There are currently only 1 to 2 leaves, which are not yet self-supporting, and should be fed with water as soon as possible. Artificially supplement the fertilizer, but make sure that the surface is not frozen. In the period of 2 to 4 leaves, apply 2 fertilizers, applying 4 to 5 kg of urea per acre.
In addition to the delay in the sowing date and the frequent cold currents, the timing of the winterization of wheat this year is very short, and the effective area is small except for a small area. Although weed grass is small, the grass is young. The amount rises rapidly. With the increase in temperature and the increase of rain after spring, the wheat field weeds will show fulminant growth and form a comprehensive grass damage. The safe and highly effective herbicides should be selected for production and the work should be carried out in a timely manner.
