The zhao jinlong summarized the characteristics of ning yi 3 and summarized its high-yield cultivation techniques, including seeding at the right time, growing strong seedlings, shifting cultivation in due time, creating reasonable planting density, managing fertilizer, scientific piped water, pest control, etc., to inform its promotion. Keywords ningdu 3 ; characteristics 3 ; high production; cultivation technology ninghu 3 is a mixed variety of pre- and post-prematured species from nanjing agricultural university college of agriculture 1 / ninghu 2 in 2007, a new type of high-quality, high-yielding and anti-super-paddy varieties were validated through jiangsu province, with high-quality rice of high quality up to the national standard 3. In 2008, it performed well as the main booster in jiangsu province, “creating a 10,000-acre demonstration area of high rice efficiency”. In 2009, this species was introduced in the city of lake ness, anhu province, and was also introduced
2. The species comparison test is summarized below in terms of its characteristics and high-yield cultivation techniques. 1. Characterization 1. 1 production 2009 experimented field at the rural institute of the city of neshu, the village of yoonlong and the county of yanjiang in the village of ninghui 3 and small area demonstration planting, the father of the town introduced 2,92 million ears/hm2, with an average of 133. 6 grains per ear, a firmness rate of 90. 2 per cent, 27. 45 g, theoretical production of 9,659 kg/hm2. According to the 18 field yield survey, the average output was 9367 kg/hm2, with an increase of 11 per cent compared to the local main plant varieties, showing a high and steady yield. 1. 2 the species is grown in single-season mid-term rice cultivation in the city of lake ness, anhui province, in mid-may, in mid-june, in late august and in mid-october. Full fertility period 151 d left
3 right, in the form of pre-cooked and late-dry. 1. 3 agronomy 3 local cultivation performance: compact, strong, prolific, principal 17 leafs, 6 long stairwells on the ground, more fratricidal, light green, medium-sweeting, high speckling, high sturdy, well-integrated, productive, 1005 cm high, and strong resistance. It's better to have one. 1. 4 resistance ninggi 3 is highly resistant to paddy folicosis. Model cultivation shows that ningdu 3 is infected with lighter rice plagues, white leaf strewn diseases, and striped leaves are not seen. 1. 5 rice quality measured by the rice quality testing centre of the ministry of agriculture, whole rice rate 65. 8 per cent, platinum particle rate 29. 0 per cent, platinum level 3. 0 per cent, adhesive density 81. 0 mm, straight chain starch content 17. 6 per cent, meeting the national standard of level 3 quality rice. Rice looks good
4 - taste and taste soft, but not hard when boiled. High-yielding planting techniques 2. 1 cultivation of sprouts at the right time 12 d, sift away. Using 25 per cent xpock 40 ml, 4. 2 per cent leachate 2 ml, 20 per cent amphibian 20 g, 6 kg of clean water is combined with solution, 4 kg of dry species, 4860 h of impregnated species, daily immersion until white. The seeding is carried out in the form of dry breeding, with attention to finely ploughing the nursery, fattening the sapling with a strong sprout, thinning the sprouts with a small amount of sprout, and with 1 hm2 fields ready to grow 5. 16. 0 m2, rice varieties 52. 560. 0 kg, strict management of water fertilizers during the shrunk season, consistent with dry sprouts throughout the course, and without watering the leaves. 2. 2 replanting in due time to form a reasonable group structure
The age limit for ningdu 3 is 2530 d and it is more appropriate to move on 1020 june. The strength of ningi 3 is such that if it is too dense, it will be difficult to take advantage of the large ears, and widening the distance between lines will help to shape the dominant groups and improve the quality and quality of products. The range of seedlings in demonstration areas is 15 cm 25 cm, with a basic seedling of 800,000 1 million/hm2, with a peak seedling of 4 million/hm2 and an effective ear control of 2. 83. 2 million/hm2. 2. 3 rational application of fertilizer 3 is moderate, with the general application of nitrogen fertilizer 240300 kg/hm2 (in pure nitrogen) and the application of a ratio of 422. 51. 5 to fertilizers (leave age 3. 54. 0) by base fertilizer. Note that phosphorus is applied in combination with potassium fertilizer, np205k2o = 10. 3
6, 0. 50. 50. 7 the phosphorus fertilizer is used as a base and potassium fertiliser is applied at the rate of 5645. In addition, attention is paid to organic inorganic fertilizer in combination with 4-5 applications. 2. 4 scientific management of moisture the first period of shallow water incubation, thin water incubation, mid-term dry wet wet and wet dry and strong rooting, when the total number of the group stalks reaches 75 per cent of the expected number of ears, when the latter period of wet irrigation is old and 10 d before harvest is cut off. 2. 5 integrated pest management pest and pest control is done in a timely manner during childbirth on the basis of forecasts from the local plant protection sector, with the pre- and post-mid-term control of grey lice, rice tremors, twilight, rice lice, etc., paying particular attention to the prevention of strangulation and cervical plague. As far as possible, high-efficiency low-resilient agents are selected for treatment. 3 references 1 lihang kim, ling, liang
