Variety source: Wuyunjing 21 // Zhendao 88/ Guandong 194, the name of the test is "Nongjing 1402"
Characteristics: Late-maturing mid-Japonica rice and early-maturing varieties. The leaves are green, the leaf posture is relatively strong, the tillering power is strong, the plant type is compact, the colony is well organized, the color changes during the mature period, and the lodging resistance is strong. The average results of the provincial and regional tests: the whole growth period is 146.5 days, which is 1.3 days shorter than the control Wuyunjing 27. The plant height is 95.1 cm, the effective ear per mu is 235,000, the total number of grains per ear is 127.7, the seed setting rate is 92.9%, and the thousand-grain weight is 27.2 grams. Appraised by the Institute of Plant Protection, Jiangsu Academy of Agricultural Sciences, the loss rate of panicle neck blast is grade 3, the comprehensive resistance index of rice blast is 4.75, moderately susceptible to rice blast, bacterial leaf blight, stripe leaf blight, and susceptible to sheath blight. The physical and chemical indicators of rice quality were tested by the Food Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs (Wuhan) in 2019: the whole rice rate was 71.7%, the chalky grain rate was 49.0%, the chalkiness was 12.7%, the gel consistency was 85 mm, and the amylose content was 10.7. %, the aspect ratio is 1.7, it is a semi-glutinous japonica rice variety.
Yield performance: Participated in the early-maturity regional trial of late-maturity medium japonica rice in Jiangsu Province from 2018 to 2019. The average yield per mu in two years was 696.4 kg, which was 6.4% higher than the control Wuyunjing 27. Participating in the production test in 2020, the average yield per mu is 683.6 kg, which is 5.6% higher than the control Wuyunjing 27. The key points of cultivation techniques: 1. Sowing seeds at an appropriate time and cultivating strong seedlings. The suitable sowing period should be reasonably determined according to the specific ecological conditions of each region and with reference to the sowing period of the main local late-maturing mid-Japonica rice varieties. Seedlings raised in plastic trays are 120-130 grams per tray, and the amount of seed used in the field is 3.5-4.5 kg per mu. 2. Transplant at the right time and plant closely. Generally transplanted in early June, the age of moist seedlings should be controlled at 28~33 days, 20,000 holes per mu, and 60,000 to 80,000 basic seedlings; machine-transplanted seedlings are 18-20 days old, and 18,000 holes are planted per mu. 60 thousand to 80 thousand seedlings. 3. Scientific fertilizer and water management. Generally, 18-20 kg of pure nitrogen is applied per mu, and the ratio of nitrogen, phosphorus, and potassium is 2:1:1. Fertilizer management masters the fertilization principle of "pre-weight, moderate stability, and post-replenishment", and the ratio of base tiller fertilizer to ear fertilizer 6:4 is appropriate, tiller fertilizer is applied early, nitrogen fertilizer is applied stably in jointing stage, and flower-protecting fertilizer shall be applied in later stage. In the management of water slurry, we should master shallow hydroponics, live trees with a small amount of water, thin-water tillers, and appropriate open fields; when the total number of stems and tillers per mu reaches 200,000, the field should be properly laid, and the later period of intermittent irrigation, dry, wet and wet strong stalks and strong roots, Water was cut off a week before harvesting. 4. Comprehensive prevention and control of pests and diseases. Before sowing, use chemicals to soak seeds to control seed-borne diseases and pests such as bakanae disease and dry tip nematode disease. Pay attention to the control of Laodelphax striatellus and rice thrips during the seedling and field stages, and comprehensive control of sheath blight, stem borers and rice planthoppers in the middle and late stages , Rice blast, etc.
Approval opinion: Approved, suitable for planting in the Yang hilly area of ​​Suzhong and Ningzhen, Jiangsu Province.
