product details
Late maturing indica three line hybrid rice.
The whole growth period is 159.6 days, 5.3 days later than Zhongyou 169. The plant leaf type is better. The tillering ability is medium, and the spike type is medium. The stem is relatively thick; The leaf color is thick green, and the sword leaf is upright; The leaf sheath and leaf margin are purple. The average plant height is 115.2 cm, the effective spike per mu is 140000, the spike length is 24.9 cm, each spike has 217.0 grains, the seed setting rate is 72.3%, the 1000 grain weight is 29.9 g, the grain type is longer, the spikelet tip is purple, and there is a little top awning. In 2015, it was inspected by the Food Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture (Wuhan): the rate of roughness was 81.6%, the rate of milled rice was 73.2%, the rate of head rice was 53.5%, the rate of chalkiness was 17%, the degree of chalkiness was 3.2%, the grain length was 6.7 mm, the length to width ratio was 2.8, the gel consistency was 50 mm, the content of amylose was 20.8%, the alkali dissipation value was 6.0, the transparency was 1, and the taste evaluation was 74.6 points. The comprehensive rice quality reached the national standard of Grade III high-quality rice.
★ Adaptability
Output performance: the average yield per mu of the late maturing group in the provincial and regional trials in 2014 was 647.09 kg, which was 5.79% higher than the control (the average within the group), reaching a very significant level; In 2015, the average yield per mu in provincial and regional trials was 598.33 kg, 4.89% higher than that in the control Zhongyou 169, reaching a very significant level. The average yield per mu in two years was 622.71 kg, 5.36% higher than that of the control. In 19 pilot projects, there were 16 increases and 3 decreases, and the number of increase points reached 84.5%. In 2015, the average yield per mu in the production test was 608.83 kg, 4.36% higher than that in the control. Four of the five pilot projects increased and one decreased, with an increase of 80%.
Resistance: The comprehensive indexes of rice blast resistance identification in 2014 and 2015 were 6.19 and 4.47, respectively. The comprehensive evaluation of natural cold resistance identification in 2014 and 2015 was weak.
★ Main cultivation measures
1. Sowing before and after the Tomb Sweeping Day, drying seeds before sowing, soaking seeds with strong chlorine, sparse sowing and even sowing, scientific fertilizer and water management, and cultivating strong tillers.
2. The method of raising seedlings shall be dry or two-stage, and the seedling age shall not exceed 40 days.
3. Reasonable close planting. The planting method is wide and narrow, with 12000 to 16000 holes per mu, and the planting density increases with the increase of altitude or the decrease of fertility.
4. Scientific management of fertilizer and water: pay attention to the bottom and catch up early, increase the application of phosphorus, potassium and organic fertilizers, and combine scientific management of water, so that seedlings can be dried in the fields, dry and wet to strengthen seeds, and achieve sufficient seedlings, healthy seedlings, large ears, and grain weight. 5. Attention shall be paid to rice blast prevention and control at seedling stage, breaking stage and full heading stage, and rice planthopper and borer prevention and control at tillering stage and booting stage. Pay attention to the control of rice blast and other pests and diseases.
★ Suitable planting area
It is suitable for the late maturing indica hybrid rice area with better heat in Guizhou Province, the area with frequent occurrence of rice blast and the area with severe autumn wind.
★ Planting season
It is recommended to sow from April 1 to April 30.
Please pay attention to sowing and scientific management according to the specific arrangements of local climate, previous crops, seedling raising mode and planting habits, and according to the accurate time guided by the local agricultural technology department.
