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, apply 1500-2000 kg of decomposed organic fertilizer per 667 square meters before applying basal fertilizer, and add appropriate amounts of calcium, magnesium, phosphorus or urea, 10 kg, calcium superphosphate 40 kg, 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. The appropriate planting period for timely planting and reasonable planting 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, after the broken membrane seedling planting seedlings to be poured after the water, 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 topdressing, early maturation, warm temperature, fear of drought, the entire growth period to keep the soil moist, especially the rising temperature after emergence, it is necessary to diligently fill small water, promote root growth, to meet the water requirement of the early maturing pupa growth period . 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. Prevention of Diseases, Prevention of Pests The diseases of Poa pratensis are bud spoilage disease and plague disease, and the diseases 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 and collect precocious crops in time, generally harvesting from June to July. At that time, 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 of strong glutinous rice. Youyou 084, a high-yielding and high-yielding hybrid rice combination with a growing period of about 130 days, is generally sown in mid-June, and the pod age is no more than 30 days. The sowing rate is no more than 15 kg/667 square meters. Uniform sowing, thin sowing, seedlings spraying at the end of one leaf stage spraying 300mg/L paclobutrazol to promote the tillers; two leaf one heart period apply "weaning fertilizer", per square meter Putian 50g compound fertilizer sprayed into a 1% solution, 3 days before transplanting, the same concentration of “send marrying manure†was applied and pests and diseases in Putian were controlled in time.
2. Reasonable dense planting, inserting the size of the basic seedling transplanting seedlings to 20cm23cm is appropriate, inserting two grain belts into each bunch, and inserting 8 to 100,000 basic seedlings per 667 square meters.
3. Scientific fertilization, reasonable irrigation in the fertilization, Shizu base fertilizer, 80kg per 667m2 special fertilizer for rice, or ammonium phosphate, superphosphate 25kg per basal fertilizer, top dressing 7d after transplanting, applying urea 15kg per 667m2, Potassium chloride 10kg, while 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.

Plant Extract has been classified to two types by extraction methods including the standard plant extract and ratio extract in china local market. If we want to distinguish between the two types ,we can see from the ingredients that we should pay attention to. The standard plant extract will be tested of its special ingredients that in the product maybe by HPLC, UV, TLC etc,but for the ratio extract,we don't pay attention to the special ingredients that in it or not,not to mention the purity of one ingredient.if you still confused about the cllasfication,pls contact us to know more.
