"Six main points" of spring rape in wheat

Early this year, early spring, the temperature rose earlier. In the spring of wheat and rapeseed, it is also necessary to highlight an “early” character in violation of agriculture. In order to win a full harvest of this year's summer crops, the “six points” were specifically proposed for the reference of farmers in the spring.

First, the implementation of classification guidance for the implementation of the classification management of wheat, rape. For all strong seedlings, priority should be given to “maintaining” and the balance of fertilizers should be implemented so as to promote stability and longevity; for all Wang Miao, priority should be given to “controlling”. For the wheat seedlings can be implemented top glutinous rice dumplings, millet, grind. For rape seedlings, appropriate nitrogen fertilizer is mainly used. We must first control and then promote; for weak seedlings, we must focus on "promoting", strengthen water and fertilizers, eat partial favors, and promote their transformation and upgrading.

Second, since the early irrigation of water to the winter, most provinces have less snow and rain and poor soil moisture. Therefore, where there are irrigation conditions, early spring night when the frozen glutinous rice is eliminated, it is necessary to give wheat early back to Qingshui. Rapeseed hi. When the temperature rises to 10°C, the canola can be returned to the blue open water. After the irrigation, the cultivator must break the clip in time. If there is rain after the spring, we must cultivator loose soil protection.

Third, early fertilization of wheat seedlings in the return period to the jointing booting stage should be 667 square meters of urea 10-15 kg plus 45% compound fertilizer 20 kg. The weak wheat seedlings should be 667 square meters of urea 15-20 kg plus 45% compound fertilizer 25-30 kg; rape in the opening period of return to the green, generally should be 667 square meters of calcium phosphate 25-30 kg plus 10 kg of urea. From the bud to the beginning of the flowering period, 667 square meters of 45% compound fertilizer 25-30 kg should be applied.

IV. Early eradication of weeds According to surveys, most of the wheat and rapeseed this year have a large number of weeds in the fields, including wild oats, Artemisia ordosica, and swine fever. Generally, during the returning green period, weeds are small and easy to kill. We can use the herbicides on the road to spray grass. Weeds in rape fields should be removed in time by cultivating.

Fifth, early spray foliar wheat from the return to the jointing booting stage can spray Bijing 5000-7500 times plus 0.3% potassium dihydrogen phosphate solution 2-3 times. Rapeseed from the green opening period to the beginning of the flowering period, the first spraying of Biqing 5000-7500 times solution plus 0.3% urea solution; the second to the third time, spraying and protecting 7500 times solution plus 0.3% potassium dihydrogen phosphate solution plus 0.2 -0.3% boron solution at intervals of 10-15 days.

Sixth, early prevention and control of pests this year, temperatures have risen early, most pests and diseases also occur early. Therefore, it is necessary to strengthen the prediction and control of wheat, rape pests and diseases. Particular attention should be paid to the control of wheat yellow dwarf disease, rust, aphids, and wheat spider mites. Symptoms such as triadimefon, imidacloprid, and chlorimazine may be used to treat the disease. Pay attention to rape virus diseases, locusts, etc., can be used symptomatic selection of poison Du Qing, imidacloprid and 48% chlorpyrifos and other pesticides, to rule early, rule small and rule.
