Multi-resistance and high-quality special wheat high-yielding cultivation techniques 2
3 pre-winter management 3.1 ensure seedlings full, Miao Qi, Miao uniform, Miao Zhuang. After the emergence of seedlings, seedlings and seedlings were removed in a timely manner. After the emergence of rain or soil very wet land plots in time to remove the compaction, ventilation protection, promote root growth. 3.2 pouring winter water once. Especially in the field of super-high yield research, the watering time is in early December, and the water is poured over the winter water in time for scratching to prevent surface cracking. 3.3 Deep cut off the roots. Since the temperature is often high in late autumn, wheat seedlings grow rapidly. For some small and prosperous plots, the plots can be effectively cut off, which can not only effectively control the population, but also improve the lighting conditions in the group and improve the vitality of the root system. The specific method is: Interdeck deep boring, depth 10cm, after the earthworms will be flattened, compacted, and then pouring winter water to prevent wind damage. 4 Spring Management (Back to Green Flag) 4.1 Up to the jointing stage, top dressing and watering. It is not mandatory to return water to the green period Mainly to carry out ploughing, to protect ventilation, improve ground temperature, promote early return to green, conducive to tiller growth, promote root development, increase the carbon metabolism of wheat seedlings, so that the steady growth of wheat seedlings. The first time in the spring, depending on the situation of lyrics, generally the wheat fields will be top-fertilized and watered at the beginning of the jointing stage. The topdressing rate of urea will be about 20kg per mu. For fields with high soil fertility and suitable groups, the top-dressing stage will be top-dressing and watering. In addition to deep-rooted land, it is necessary to carry out chemical control. 4.2 Watering flag or flowering water. Flag-shooting period is the critical period of wheat water demand. Watering flag water can effectively reduce the degradation of small flowers and increase the number of grains per spike. 5 Late-stage management (a mature period) The key to late-stage management is to increase the group's photosynthetic potential, keep the green area and photosynthetic rate as high as possible, and ensure that the grain weight can reach 48g or more. 5.1 timely control of pests and diseases. First of all, do a good job in predicting pests and diseases, determine the appropriate period of prevention, and adhere to the "prevention-based, comprehensive prevention and control" strategy. Liaomai No. 18 has strong resistance to disease. After the seeds are treated with the coating, reasonable cultivation measures are adopted. Before the heading, the occurrence of pests is generally light; when the heading temperature is low, the density of the aphids is high and the damage period is long. The acetamiprid is used. Such pesticides or compound pesticides can effectively control aphid damage. 5.2 foliar spray fertilizer, improve wheat quality. After flowering of wheat, when the plant nutrition is poor, 0.2% 0.3% potassium dihydrogen phosphate solution, 1%-2% urea solution or 2%-4% superphosphate solution are sprayed after flowering to the early stage of grouting. Acres 75-100kg, spray two or three times, each time around a week, can significantly increase wheat grain weight and grain quality, delay aging. 5.3 The wax is ripe at the end of harvest and wheat straw is returned to the field. When the wax was cooked at the end of the harvest, the grain weight was the highest, and the nutritional quality and processing quality of the grain were the best. The use of combine harvester to achieve straw return, can effectively improve soil fertility. Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff Valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
