Rice No-Tillage Seedling Cultivation Technique I. Rice no-tillage cultivation Rice no-tillage seedling cultivation technology is based on no-tillage principle, combined with rice throwing technology and a kind of cost-effective, safe and protective tillage technology. The so-called rice no-tillage cultivation technique means that after harvesting the last crop, the soil is not ploughed, and when the field is dry or waterless, the herbicide is applied first to kill the green crops such as field weeds and crushed rice piles. Afterwards, water is soaked in the fields and fertilized. After the water layer is naturally dried, a light, cost-effective, simplified, and highly efficient technique for rice throwing, transplanting, or direct seeding is performed. 1, no-till throwing. No-tillage seedling transplanting is after the harvest of the previous crop (rape or wheat), direct spraying herbicides - "Kirgo" and then throw the seedlings directly on the field without cultivation. The procedures for no-tillage and seedling dumping are: harvesting rapeseed (wheat) - spraying herbicides (clones) - irrigation of horse water - applying base fertilizers - tidying up the earthworms - throwing water for 1 to 3 days before rehydration (watering slowly, to prevent Rinse) - Herbicides are routinely applied after returning green - routine management. No-tillage seedlings should be paid attention to: the number of throwing acupuncture points per acre more than ploughing 5-10%, Daejeon base fertilizer to maturity, to prevent the phenomenon of burning dead seedlings. No-tillage seedlings are better at compound fertilizers, and it is better not to use ammonium bicarbonate or less. 2, no-tillage transplanting. No-tillage transplanting is after the previous crop (rape or wheat) is harvested, directly spraying the herbicide - "Kirgo", the seedlings inserted in the field without cultivation. For no-tillage, the soil with soft soil and light loam should be used. The procedures for no-tillage and transplanting are: harvesting rapeseed (or wheat)—spraying with herbicides (Kerrigin)—instilling horse water—applying base fertilizers—arranging fieldworms—transplanting rice plants 1–3 days later, rehydration—applying rice field herbicides as required—regular management . When replanting after transplanting, water should be slowly poured to prevent floating. 3, no-tillage live. No-till live broadcasting is the direct spraying of herbicides after the harvest of the former crops (rape or wheat) - Krishna, and the rice seeds are sowed directly on the fields without plowing. The procedures for no-tillage live broadcasting are: harvesting rapeseed (or wheat)—spraying herbicides (Kreiger)—irrigation of water-swollen fields—basing of fertilizers—ordering of ridges—ploughing of fields—sowing—application of live rice herbicide—regular management. No-tillage live broadcasting should pay attention to two points: First, the amount of sowing is a little less than that of plowing; and second, do not use paddy fields and insufficient water sources. Second, the rice diskless throwing Rice seedless discontinuation technology is the use of "dry nurse nanny" super absorbent seed coating agent for seed coating, the implementation of dry seedlings. “Dry nurse nanny†can form hygroscopic mudballs with a diameter of 2.5-3.0 cm at the roots of seeds and seedlings to form a practical technique with soil throwing and easy to throw. This method does not use sampan plates, is not limited by age, is not subject to geographical restrictions, is cost-effective, simple, and easy to implement. It is another major breakthrough for paddy rice breeding. Dry nurses use technology. 1, selected models. Rice "dry nurse nanny" models are mainly throwing and planting type. 2, determine the amount of seeding. Each kilogram of dry nurse nanny coated rice 3 kg, drug ratio of 1:3. 3, soak the seeds. Use the current method of coating the seed. Before sowing, the rice seeds are soaked in fresh water for 25 minutes to 12 hours. The rice seeds are then removed and drained. 4, coating method. The coating agent is poured into a smooth garden type container, and the soaked rice seeds are slowly added into the container for rolling coating, and the container is stirred or shaken while adding the seed until all the coating agent is wrapped on the seed. 5, seedbed selection: Park field, dry fields, Putian after winter mulberry after the top soil loose layer weeds can be a small field. 6, pouring enough water. The bottom water of the dry nursery bed should be poured in one step to make the water in the seedbed reach saturation in 0-10 cm soil layer. 7, even sowing. The seedless seedling must be evenly planted in order to achieve a relatively uniform mudball size in the seedlings and to increase the seedling establishment rate. 8, cover fine soil immediately after sowing. After sowing, the seedbed should be covered with fine soil and then wetted with a watering can, then sprayed with a special herbicide for arid field. 9, cover the film, warming and moisturizing. In order to ensure that the seedlings are homogeneous, uniform and strong, the film should be covered immediately after sowing, and the film should be gradually removed after the seedlings are filled, and moisture should be supplied once. 10, seedless seedlings in the afternoon of the day before the allocation of water to be poured once permeate, once through the earth, to ensure that when the allocation of earthworm seedlings with a suction ball at the root. 11, pay attention to the prevention of dry soil pests.
