In order to adjust the structure of the agricultural industry, increase land use efficiency, and increase the multiple cropping index, the first rice crop of Huaqiao Township, Songxi County, Fujian Province was used as early maturing rice and tobacco and rice, and it was cooked for one year and two crops. The yield per 667 square meters of Poa pratensis can reach 1500-2000kg, and the late rice can reach 500-550kg. The techniques for high-yielding cultivation of early-season waxy rice and rice rotation are introduced as follows: First, early maturing cultivation techniques 1. Fine soil preparation, full base fertilizer Before deforestation, apply 1500-2000 kg of decomposed organic fertilizer per 667 square meters, and add appropriate amount of calcium, magnesium, phosphorus or urea 10 kg, superphosphate 40 kg, and potassium chloride 15 kg as base fertilizer. After the plots have been ploughed and sun-dried, the plots are single-ridged. In the soil preparation, depending on the nature and conditions of the soil, 50-70 kg of 667 square meters of lime can be applied for soil improvement to improve soil structure. 2. Timely planting, reasonable close planting The suitable planting period of Poa pratensis is from mid-November to mid-December. After planting seedlings, cover the mulch completely. Density 3000 to 3500 strains/667 square meters. 3. Careful management, broken membrane seedlings After planting seedlings, foot water should be poured to ensure emergence. If the temperature is high, the water evaporates quickly, the soil is too dry, and there is no condensation on the surface of the mulch during the day. Water should be applied along the gingival sulcus once. After the beginning of spring, the buds are gradually unearthed. During this period, they should often go to the field and find that the unearthed seedlings should immediately break the membrane and apply seedlings. Membrane breakage time is appropriate before 10:00 am. You can tear the mulch directly by hand, remove the seedlings, and then seal the seedlings with fine soil to prevent water loss and reduce soil temperature. 4. Scientific irrigation, reasonable top dressing Early-maturing cultivars are afraid of drought. The whole growing season should keep the soil moist, especially after the emergence, and the temperature should be raised gradually. It is necessary to dilute the water and promote the growth of the roots to meet the moisture requirement of the early-maturing pods. When it grows to 4 to 5 leaves, it begins to enter a vigorous growth stage, and the leaf area increases rapidly, requiring more water. In this period, water should be properly controlled to prevent overgrowth on the ground. After the 7th leaf stage, sufficient water is supplied to increase the yield and quality of the early maturing pods. Precocity requires large amounts of fertilizer, in addition to the application of base fertilizer, it is generally top dressing 3 times. The first time to raise Miao Fei, after the leaves spread urea 10 ~ 15kg per 667 square meters, superphosphate 15 ~ 20kg, mixing evenly after pouring water, promote root growth; the second time dressing in the 3 to 4 leaf stage , Combined with cultivating earth urea 10kg per 667 square meters, ternary compound fertilizer 15kg, to provide sufficient nutrients for the rapid growth of bluegrass. The third topdressing stage in the 7th leaf stage, combined with the ditch cultivation soil (using the soil in the ditch for soil cultivation) to be re-applied, applied Sanyuan compound fertilizer 25kg per 667m2, potassium chloride 10kg, this period is the early growth stage With the prosperous period of fruit and vegetables, top dressing is the key to improving yield and quality. 5. Disease prevention, pest control The diseases of Poa pratensis are bud spoilage and plague, and the disease should be mainly prevention. At the time of onset, 65% wettable zeocin can be used 500 to 600 times, or 70% thiophanate-methyl 500 times spray to prevent and control; pests mainly include aphids, thorn moths, cockroaches, red spiders, etc. Fruit emulsion 500 to 1000 times, 80% dichlorvos 1000 to 1500 times or 50% phoxim 2000 times spray. 6 pay attention to the market, timely harvest Poa pratensis is generally harvested from June to July, when it was the off-season supply of vegetables. Markets should be harvested in time according to market conditions. Second, late rice cultivation technology 1. Timely sowing and cultivation The IIyou 084, a high-yielding and high-yielding hybrid rice combination with a growth period of about 130 days, is generally sown in mid-June, and the seedling age is no more than 30 days. The seeding rate is not more than 15kg/667 square meters. The seedlings were sprayed with 300 mg/L paclobutrazol to promote tillering at the one-leaf stage; the “frosted manure†was applied at the two-leaf and one-heart stage; 50 g of compound fertilizer was sprayed on a 1% solution per square meter of paddy field, and the same concentration was applied 3 days before transplanting. "Send marriage fat" and timely control of pests and diseases in Putian. 2. Properly dense planting, insert the basic seedlings Transplanting specifications to 20cm23cm is appropriate, each cluster insert two grain glutinous rice vines, every 667 square meters insert 8 to 100,000 basic seedlings. 3. Scientific fertilization, reasonable irrigation In fertilization, apply enough basic fertilizer, apply 80kg of special fertilizer for rice per 667m2, or apply 25kg of ammonium phosphate and superphosphate, apply fertilizer 7 days after transplanting, apply 15kg of urea per 667m2, and mix potassium chloride 10kg. Butachlor 0.2kg weeding. After transplanting rice for the second time after 15 days, applying urea 5 to 10 kg per 667 square meters and potassium chloride 5 kg. In the middle and late stage, paddy fields should be fertilized as appropriate, and the total fertilization amount should be 12 kg of pure nitrogen per mu, and the ratio of nitrogen, phosphorus and potassium should be 1:0.5:0.7. When the number of pods reaches 70% to 80% of the number of seedlings to be planted, the field can be roasted, and the effective tillering is strictly controlled to increase the percentage of spikes. In the later period, wetting and drying alternates to prevent premature water cut and increase the seed setting rate. 4. Prevent pests and diseases. The main pests of timely harvesting II You 084 include rice planthopper, rice borer, rice borer, rice leaf roller. Diseases mainly include rice smut, rice blast, and sheath blight. According to the forecast and forecast of the local plant protection department, pest control should be done in time to ensure high yields.
