Rice intensified cultivation technology is a new rice cultivation technology that our province vigorously promotes. It adopts the method of ultra-deep planting and single plant cultivation, and pays attention to the individual advantage, so that rice has a large growth space, can obtain more sunlight and air, is conducive to the development of roots and canopies, and thus produces more tillers and Effective ear, to reduce the use of species, increase production and improve quality. This year, the county has promoted 21 acres of cultivated area in Sanmingshan Town, Xijiashan Town and Tonglu Town. Among them, 12 mu of Simianshan Town, 5 mu of Tonglu Town, and 4 mu of Xijiashan Town. Transplanting standards uniformly adopted a transplanting density of 50 cm and 50 cm, planted single seedlings, single nests were planted in triangles, transplanted with leaf age of 3 leaves, and transplanted plots of winter paddy fields. Has entered the end of childbirth, no sitting, no pest damage, growth, looks good. In order to explore the mechanism of yield enhancement in rice intensification, I stationed Lixing Household in Qili Village of Simianshan Township as the designated observation household for enhanced cultivation of rice, and established a comparative experiment of intensified cultivation and wide and narrow row cultivation of rice in the same field. The area of ​​2.5 acres of land, before the winter paddy field, the light to the wind, irrigation and drainage is convenient, fertile soil. The cultivar was ii You 725, which was sown on March 5th and wetted with pods. It was planted on April 10 and planted with leafage of 3.4 leaves. Mushi planted in the field and planted 1,000 kg of manure, 300 kg of plant ash, and 15 kg of calcium, magnesium and phosphate fertilizers as base fertilizers. They were plunged into the fields one day before planting. Ten days after transplanting, 5 kg of urea was applied as a top dressing, 20 days after transplanting, and 5 kg of urea was applied again. In Daejeon, shallow water was used, and “tricyclazole†was used to control rice blast at the seedling stage. At the end of April, the aphids were controlled with special killing crickets. Intensified cultivation area of ​​rice is 1 mu. The planting specifications are 50cm50cm. The rows and rows are equal to squares. The number of acres per plant is 2666.67 nests, and the single nest is planted with 3 seedlings. The distance between single seedlings is 9cm. 8000.01 seedlings. Wide and narrow line cultivation area of ​​1.5 acres, using the (12 +6) / 28 inch specifications, acres of planting 8333.33 nest, nest flat planted two seedlings, mu basic seedlings for 16666.66 seedlings, every row of 6--8 rows of rows of japonica rice. The number of cultivated nests in rice intensified cultivation was 5662.66 litters less than that in wide and narrow rows, 68% less, and 8866.65 acres less in basic seedlings, 52% less. On May 21st, in the investigation of the field plot, 19.6 seedlings were planted in potted plants, the number of tillers per plant was 6.5, and the seedlings per mu were 52,266.73. The wide and narrow row of cultivated nests reached 8 seedlings, with 4 seedlings per plant, and 66666.64 seedlings per mu. The survey results showed that the number of rows of rice intensified cultivated per acre was 11.6 more than that in the wide and narrow rows, which was 145% more; the number of tillers per plant was more than 2.5 seedlings, which was 62.5% more; the number of basic seedlings per acre was 14399.91 acres, which was a small 21.6%. On June 8, the number of seedlings in potted rice was enhanced by 32.1 seedlings, 10.7 seedlings per plant, 85,600.11 seedlings per acre, and 9.7 seedlings in a wide and narrow row. The number of tillers per plant was 4.9 seedlings. 80833.3 seedlings. The survey results showed that the number of rows of rice intensified cultivated per acre was 21.4 more than that of the wide and narrow row, which was 200% more; the number of single tillers was 5.8 more, which was 123.4% more; the number of basic seedlings per mu was 4,676.81 acres, which was 5.9% more. The cultivation of wide and narrow rows of rice has more than double the number of mu nests, more than double the number of acres of basic seedlings. Rice intensification is compensated by the strong tillers of each plant. Ultimately, the basic seedlings for rice intensified cultivation exceeds the width and width of rows for cultivation. High-yielding laid a strong foundation. The main focus of our later management is: drainage control, fertilizer and water management, pest control, and ensuring the harvest of rice.
