High Quality seeds of You Need

Characteristics:

Indica three line hybrid rice varieties. In the upper reaches of the Yangtze River, the whole growth period of a season of medium rice was 152.6 days, 2.8 days shorter than that of the control Ⅱ You 838. The plant height is 111.3 cm, the spike length is 24.8 cm, the effective spikes per mu are 143000, the total grains per spike are 174.8, the seed setting rate is 85.4%, and the 1000 grain weight is 30.6 g. Resistance: the comprehensive index of rice blast in two years was 4.2 and 5.7, respectively, and the loss rate of ear blast was the highest in seven grades; Brown planthopper 9; Susceptible to rice blast and highly susceptible to brown planthopper. Main indexes of rice quality: head rice rate 53.5%, length width ratio 2.9, chalky grain rate 44%, chalkiness 7.4%, gel consistency 71 mm, amylose content 18.7%.

Yield performance:

participated in the regional test of the mid indica late maturing group in the upper reaches of the Yangtze River in 2013, with an average yield of 617.1 kg per mu, 5.6% more than the control Ⅱ You 838; In 2014, the average yield per mu was 627.0kg, 8.4% higher than that of IIyou 838; The average yield per mu in the two year regional test was 622.0 kg, which was 7.0% higher than that of IIyou 838. In the production test in 2015, the average yield per mu was 620.7kg, 7.1% higher than that of IIyou 838.

Key points of cultivation technology:

1. Sow early at the right time and cultivate strong tillers.

2. Transplant in a timely manner, with seedling age of 30-40 days, planting about 15000 holes per mu, planting 2 grain seedlings per hole, and basic seedlings of 60000 to 80000/mu.

3. Formulated fertilization, heavy base fertilizer, early topdressing, late stage supplement of ear and grain fertilizer according to seedlings, 10-12kg of pure nitrogen per mu, and reasonable combination of nitrogen, phosphorus and potassium fertilizers.

4. Turn green in deep water, tiller in shallow water, sun seedlings in time, keep the shallow water layer in booting and heading stage, and alternate dry and wet in filling and fruiting stage. In the later stage, do not cut off water too early. 5. Pay attention to the timely prevention and control of rice blast, sheath blight, rice false smut, borer and other diseases and pests.
