High Quality All Natural Rice Seeds

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 156.5 days, 0.9 days longer than that of the control Ⅱ You 838. The plant height is 120.2 cm, the spike length is 26.5 cm, the effective spikes per mu are 138000, the total grains per spike are 202.4, the seed setting rate is 74.1%, and the 1000 grain weight is 32.3 g. Resistance: the comprehensive index of rice blast in two years was 3.8 and 4.2 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 50.1%, length width ratio 2.6, chalky grain rate 63%, chalkiness 10.9%, gel consistency 61 mm, amylose content 21.2%.

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 622.6kg per mu, 5.6% more than that of the control Ⅱ You 838; In 2014, the average yield per mu was 622.5kg, 9.4% higher than that of IIyou 838; The average yield per mu in the two-year regional test was 622.5kg, 7.5% higher than that of IIyou 838. In the production test in 2015, the average yield per mu was 627.5 kg, 8.0% higher than that of IIyou 838.

Key points of cultivation technology:

1. Sowing early in time and cultivating strong seedlings; The seed consumption is 0.75-1.0 kg/mu, and the seeding amount per mu is 7 kg/mu.

2. Transplant timely, with seedling age of 30-40 days; 12000 to 15000 holes are planted per mu, and 2 grain seedlings are planted in each hole. The basic seedlings are 60000 to 80000/mu.

3. Pay more attention to the bottom and apply fertilizer early. The ratio of base fertilizer to top fertilizer is 7 ∶ 3, and the ratio of nitrogen, phosphorus and potassium is 1 ∶ 0.5 ∶ 0.8.

4. Frequently irrigate in shallow water, transplant seedlings in shallow water, turn green the living hill in inch water, and thin water promotes tillering. About 20-25 days after planting, the seedlings shall be controlled according to the situation of the seedlings. The shallow water layer shall be maintained from booting to heading and flowering. After the ears are full, sufficient water shall be filled. Later, the seedlings shall be dry and wet until they are ripe.

5. Comprehensive pest control, mainly including rice blast, sheath blight, rice false smut, rice thistle, rice leaf roller, rice stem borer, rice stem borer, rice planthopper, etc.

6. Timely harvest to ensure high quality and yield.

7. The seed setting rate of this variety is low. Pay attention to the influence of abnormal temperature during heading and flowering.
