Wu Yuxi No. 14 Throwing Point
In order to realize the goal of Wuyujing No. 14 per mu with a yield of 600 kg or more, it is necessary to focus on the cultivation of age-appropriate strength and strength, and on the basis of guaranteeing full-spike, the main attack should be large spikes and increase the grain weight by 1,000. The main points of his post-planting are as follows: 1. To cultivate age-appropriate seedlings and plant seedlings in a timely manner. Daejeon uses the amount of control at about 2 kg per mu, mastered on May 30 or so sowing, do a good job of seed treatment, seed soaking with a pack of 1 half and half water to 10 kg of rice immersed 6 kg. Fill 70-80% of the holes with fine mud. It should not be overfilled to prevent rooting. It is necessary to strictly control the management of the water slurry, and the emergence stage should not be preceded by the plastic tray water supply, and the weaning fertilizer should be chased after one leaf and one leaf, and the thin water layer should be established during the two leaves and one heart period. Age 16-18 days, leaf age 3-4 leaves throwing plant, throw 70% first, then throw 30%. The first toss should be thrown high and throw far behind, and the later thrown near should throw evenly to fill the gap. The density per mu is between 2 and 240,000 points, and the basic seedlings are between 8 and 90,000. After the dredging is completed, open 2 operation ditch in the field. 2, scientific management of fertilizer, improve the rate of tilling and spike. The management of the throwing rice cultivation is based on the goal of "sufficient seedlings on time, medium-term strong stalks attacking big spikes, late-ageing sensation and not greediness in the later period" as a goal, and managing water well with good fertilizers. Doing a good job of water slurry management due to rice seedling transplanting Shallow, irregular hole distance, in the live tree stage should be shallow water during the day, drained water at night. After throwing seedlings, shallow water ground irrigation to promote the delivery, enough time to dehydration after the seedlings in a timely manner, so that early delay, light hold, More than one place, to prevent the group from becoming too large, to promote deep-rooted roots, to be wet and dry during the later period of childbearing, and to avoid flooding and flooding to prevent lodging. In terms of fertilizer management, Datian uses 19-20 kilograms of pure nitrogen per acre. The basal fertilizer and tiller fertilizer are controlled at 60% of the total fertilizer amount, and the long crude fertilizer and panicle fertilizer are controlled at 40% of the total fertilizer. 3) Comprehensive prevention and control of diseases and insect pests should be carried out. Agents, before it should pay attention to the occurrence of rice weevil, timely medication control, late to pay attention to the occurrence of sheath blight, and effectively prevent and cure pests.
