Wheat in paddy grain field optimization supporting technical regulations
The integrated wheat cultivation is an optimized system project to achieve the annual high-yield ton field, and its output requirements are: 600-650 kg wheat yield and 350-450 kg dry rice. The present practice of combining the cultivation of the Science and Technology Park of the Institute is as follows: 1. During the ripening season, the climate conditions in various regions shall be allocated. The choice should be made to start with the matched varieties of the crops. This is the primary condition for realizing the balanced production increase of the two crops. 1, early maturing wheat deployment of medium-maturing dry rice varieties: wheat should be selected June 10-12 maturation, yield more than 550 kg of varieties (such as the new lines of the new wheat No. 38, Zhongmai No. 9, Zhongda No. 10, etc.); In northern provinces such as Beijing, Tianjin, Hebei and Liaoning provinces, sowing droughts No. 9, 51 and 65, and Huanghuai and Jiangnan provinces selected drought 44; middle drought 502 and medium drought No. 14; 2. Early maturing of middle-maturing wheat. Upland Rice Variety: Wheat is selected from June 15th to 18th and matured, yielding more than 650 kg extra large grain 86 (79), Tackling No. 1 or China Super Wheat 906 and other high-yield and ultra-high product varieties. The drought-tolerant rice crops in the north, northeast, and northwest regions of China should use Zhonghan No. 10, No. 11 and Chaofengzao No. 1; Huanghuai and Jiangnan provinces should choose sowing Zhonghan No. 227 and No. 297 as the most suitable. Second, optimizing seeding to ensure wheat and rice double cropping, and selecting the best sowing date is crucial. The sowing period for wheat with an output exceeding 500 kilograms per mu is generally from September 26 to October 4. The ploughing period for the upland rice follows the June 4th to 8th before the wheat harvest the following year; if it is harvested, it will be followed by the live broadcasting with drought, not later than June 15-20. Before sowing wheat, wheat must be sown for 48 hours. After drying, wheat can be directly mixed with herbs and rice seeds must be soaked. Carbendazim 500 times the general use of soaking seeds for 24 hours, or soaked with 1%-2% lime water for 48 hours, remove and drain the water and then mix with biological potassium fertilizer timely enough. Wheat should be semi-precision sowing, mu sowing 10 kg, with a size of 1015 cm spacing sowing seed; dry rice paddy field set 6-8 kg. With live pod or dry rice pure 10 kg per acre is appropriate, spacing of about 26 centimeters, are the next species in the wheat maggots. Third, supporting fertilization due to the following year, wheat indica rice inconvenience to apply basic fertilizer, can be adjusted during the breeding of fertilizer matching standards to meet the nutritional balance of the two crops. The matching fertilization standards are as follows: 5 kg of farmyard manure, 30 kg of diammonium phosphate, 50 kg of ammonium bicarbonate, 40 kg of potassium chloride, 2 kg of zinc sulfate, and 25% of ferrous sulfate per hectare. Ammonium-mixed applicator) applied one time; wheat was not top-dressed during the whole growth period, and potassium dihydrogen phosphate was sprayed 2-3 times as appropriate after 5 days of flowering. Maize upland rice enters the jointing stage to protect the accumulation of nutrients during the booting stage; from booting to flowering stage, the foliar spray is applied 2-3 times (1 kg of potassium dihydrogen phosphate per acre is used to dilute water to 50 times), which has obvious increase in grain growth. Heavy effect. Infertile paddy fields should be given organic fertilizer, phosphorus and potassium fertilizers, iron and zinc supplements, etc. during the jointing stage. Fourth, water-saving irrigation wheat to regulate nutrient, pay attention to pouring frozen, jointing and booting water, do not return to Qingshui, discretionary control of pouring yellow wheat water. Do not arbitrarily increase the number of watering in order to prevent the late harvest of greed, affecting the timely broadcast of the upland rice. After sowing the rice, if it happens to be dry and dry, there is no irrigation condition, so it can wait for the rain to emerge; if it can be irrigated, once the head water can be raised. Based on the stubborn drought-resistance of dry rice, sandy soil was drought-bearing for 15-20 days at seedling stage, and viscous soil was watered once at the first month of drought. After jointing-drying for 10 days, it was combined with top-dressing fertilizer and then poured into big water twice. From heading to grouting, it is the peak period of key water use during the whole life of the wheat glutinous rice, and it is also the transitional period from vegetative growth to reproductive growth. In case of continuous drought for more than 7 days, it should be irrigated immediately and should not be subject to drought; if the rain is frequent in the autumn or in the long-term, wet and haze, it can be poured without water. In general, there is no need to irrigate some low-lying lands in dry areas in the southern rainy areas or in the arid areas in the north. In summary, regardless of wheat and upland rice, irrigation can be carried out for 3-4 times during the whole growth period. Whether or not two crops need to be irrigated and irrigated in their growth stages depends on the rainfall distribution, size, soil moisture, and seedling conditions. However, its high-yield approach is based on re-sweetwater-saving and sprinkling and headwatering, aiming at increasing grain size and improving quality and yield. V. Chemical Weeding Before the removal of wheat, general removal of large grasses is usually followed by "soil sealing" or "stem and leaf treatment." Wheat is usually digested before the Ching Ming Festival with “Tribenuron-Sulfuronâ€, and all wheat growers are in control. Therefore, the amount and method are not described. Upland rice was blended with 100% of 12% EC 200 times solution of "Nongsi", 100% solution of "Dioxin" 20% EC or 100% of "butachlor" 60% EC. It is best to spray after the rain or after the water has been wet. To prevent the drug from evaporating, damaging the film and reducing the efficacy. Must pay attention to strictly control the amount and concentration, otherwise it is easy to cause dead seedlings phenomenon. VI. Insect Pest Control The wheat-rice integrated cultivation and the control of Maibao Rice are the most important to control the occurrence of wheat aphid and wheat from dwarf disease. Markets around the world have "Amine Phosphorus," "Omethoate," and "Wheat from the dwarf" agents, the dosage of which is detailed in the instructions. Few rice blasts occur in the northern arid areas of Beijing, Tianjin, Hebei and Liaoning, but attention should be paid to rice weevil control during the seedling stage. It is sprayed with 2000 times the "methyl ethyl thioether EC" seedling. Huanghuai and the south of the Yangtze River should pay special attention to the prevention of rice leaf roller and rice stem borer, and they should be controlled once every 7 months from the beginning of July to the same month, and they should also be used to treat rice borers, stem borers and rice planthoppers. The methods and methods used in the rice area are basically the same as those in the rice, and the northern area in the dry grain can be replaced by a broad-spectrum insecticide such as wheat and corn. In some areas, upland rice also needs to prevent rodents from harming during the late growth period. Upland rice cultivars are conventional species, and rice can be planted for successive years, but it is necessary to purify and rejuvenate the field in order to maintain seed purity. Upland rice is also fertile and transplantable, and it is planted and managed like rice. It is more drought- and water-saving than rice during the middle and late stages of growth. Although the tillering rate is low, the growth is lush.
