Watering drought. In paddy fields, irrigation conditions must be filled with water and drought as much as possible, and the trend of spread of drought should be firmly curbed. No-tillage rapeseed in paddy field is suitable for irrigation and drought resistance, and it can be used for furrow irrigation. The water is poured into the depth of 2/3 of the ditch so that the water can penetrate the moist soil. However, it is necessary to prevent submergence, flood irrigation and long-term irrigation so as to avoid lack of oxygen in the soil. When cultivating live or transplanted rapeseed, it is easy to cause soil subsidence and damage the root system. Pay attention to the method, but it is best to take the same method as dry soil rape, and combine it with fertilization. Some rape fields cannot use irrigation because they have no water or high irrigation costs, and they can't even water and drought-resistant. They can spray fulvic acid on the foliage (also known as drought-resistant agent No. 1 and FA “green fieldâ€). It is 1000 times liquid to 1200 times liquid. Covering the rows with coverings can effectively reduce soil moisture evaporation and improve drought resistance. Cover can be used straw, wheat straw, leaves, etc., thickness of 6 to 8 cm, not only drought, but also significantly antifreeze.
Rilled soil. Rapeseed has a well-developed root system that not only improves antifreeze capacity, but also absorbs deep soil moisture and improves drought resistance. However, in the early days of cultivating, attention should be paid to methods, methods are improper, and counterproductive. The biggest difficulty in cultivating the arable land in winter is that the rapeseed soil cultivated in no-till field is hardened and hardened. Shallow can be done first, cut off the capillary, reducing evaporation. With conditional irrigation, it is possible to deeply dig oilseed rape after irrigation and when soil moisture is good, creating a good soil environment for root growth. Plowing rapeseed field, shallow soil, crushing soil blocks, reducing large gaps in the soil and reducing soil moisture evaporation. The cultivator should be carried out at a high temperature before winter, which will help increase the soil temperature. In combination with cultivator, earthworms are cultivated to prevent cold weather from invading the rapeseed roots.
Top dressing promote seedlings. The high temperature before winter is an important period for winter rape, and it is necessary to timely raise fertilizer and promote seedling growth. Topdressing can be carried out alone or combined with irrigation (watering) to combat drought. For example, when top dressing is combined with irrigation, urea 7.5 to 10 kg (or 15 to 20 kg of ammonium bicarbonate) and potassium 5 to 7.5 kg may be topdressed before 667 m2 of irrigation, focusing on thin and thin seedlings. However, it is best to apply water to fertilize the fertilizer to form a thin fertilizer solution, which can achieve even fertilization, but also facilitate root absorption and utilization, and improve fertilizer utilization. At the same time, spraying 0.5% urea, 0.3% potassium dihydrogen phosphate and 0.1% borax mixed liquid on thin leaf surface two or three times, spraying once every 5 to 7 days.
Antifreeze protection seedlings. Before winter, the temperature is too high, and we must beware of the sudden drop in temperature causing freezing damage. In mid-to late December, half-cooked pig cattle and manure compost should be applied in a timely manner, and frost and ash in firewood and ash can be applied next to the earthworm. Due to the high temperature before the winter, it is necessary to prevent early rape. After suffering from frostbite, it may affect the entire plant. For picking up early on, pick it up on a sunny day.
The greenhouse support line is used for the plant that stands tall on its own. The support will keep your plants healthy and upright. This economical and efficient support system will wow you.
