First, timely cultivator planning and planning has the effect of raising temperature, keeping cerumen, promoting weak growth, and promoting early-onset root growth. In early spring, it should be avoided in order to prevent injury to the roots and the cold, and timely planning should be done after watering and raining. In particular, the three types of small fields should be planned early to promote the rapid escalation of the wheat seedlings and strive for more tillers. , to ensure sufficient acres of mu.
Second, the local governance should pay attention to the spring fertilizer for the pre-winter growth is good, the current lyrical and good one or two types of wheat on the basis of the protection plan, as far as possible to delay the time of watering and fertilization to the jointing period, time in April Early days. The three types of wheat fields with the number of mu stems below 600,000 and the first and second types of wheat fields that are partially damaged due to poor soil preparation and planting quality can be well-watered from the middle of March to the end of March. 15 kilograms of urea promotes the growth of tillers in spring, increases the percentage of tillers and spikes, and increases the number of panicles.
Third, timely control of pests and weeds For many years of heavy cropping, last year, wheat sheath blight, root rot occurred in the plot of land, from the turning green period, spraying 20% ​​triadimefon 1500 times liquid to prevent disease. After the return of green wheat, most of the weeds also began to grow green. At this time, the weeds were small, the resistance to insecticide was poor, and the weed control effect was good. Weeds in the wheat field should be treated with 10% tribenuron-methyl or wheat giant 10-15 grams for the prevention and control of the plots. The main crops are grasses including barley, wild oats, and other weeds. Should be selected 6.9% of hummer cream or 3% sema cream spray control, time in mid-March.
Fourth, pay attention to the prevention of wheat bush dwarf disease In recent years, with the increase in the warm winter years and the reform of the farming system, the incidence of wheat bush dwarf disease has rebounded, due to late last year sowing area sowing time, weak seedlings before the winter Due to the large area and the decline in disease resistance, attention should be paid to the prevention of wheat bush dwarf disease. The specific method is: the wheat returns to the early Qing Dynasty select windless sunny weather, each sprayer with 10% of imidacloprid 10 grams add 4.5% of beta-cypermethrin spray wheat and cornfield 30 ml, can also be used 40% omethoate sprayer spray 30 ml of medicine, When a large number of Laodelphax striatellus (more than 8-10 head per square meter) should also be added to prevent disease and other diseases, 1.5% Zhilingling No. II or fluoromorpholine, to improve the control effect.
Fifth, pay attention to spraying regulators for the prevention of some groups of large wheat fields, the risk of lodging in the latter part, should be up to the joint before the mu with 30-60 ml of wheat Jinde or 15% paclobutrazol 40-50 grams of chemical control To shorten the length of the base 1-2 festivals, to prevent late lodging.
