Rice-field rapeseed direct seeding and early buds can seriously affect the yield and quality. There are many reasons for this. In the practice, the author finds that adopting the following “eat a small stove†approach can prevent the impact of rapeseed buds on yield. (1) Pick buds. When the moss is about 15 centimeters high, the top of the bud is removed 3-5 centimeters, and the operation is performed after the sunny dew is dry. After picking the cockroach, 50% of the carbendazim 150-200 grams of water is used to spray 50-60 kg of water. To prevent germ infection. (2) cultivating earth. The cultivating soil in the cultivator can loosen the soil layer, remove part of the old roots, suppress the growth and development of the shoots for a short time, and promote the rapid growth of new roots; enhance the permeability of the soil, facilitate the deep rooting of the roots, and enhance the ability of drought resistance. (3) spraying plant growth regulators. For the base fertilizer, there are many nitrogenous fertilizers and the seedlings are prosperous. The plant growth regulators can be used for chemical control. Generally, 15% paclobutrazol per mu can be used to spray 50 kg of clear water on the foliage. (4) Topdressing quick-acting fertilizers. After top dressing, topdressing can be combined with the total amount of catching manure to regulate. The average field of moderate fertility and seedling potential is 300-400 kilograms of manure and 300 kilograms of compound fertilizer, and 10 kilograms of compound fertilizer is applied to clear water. The base fertilizer is high in fertility, and the fertility is high. . Simultaneously spraying foliar fertilizer, after harvesting, the mu is applied with foliar potassium dihydrogen phosphate 150-200 g, urea 500 g water, 50-60 kg water, or sprayed with plant nutrient solution.
