All Natural Hybrid Rice Seeds Market

Zhuliangyou 35 is the Chinese Rice Research Institute, and it uses Zhuliangyou 1S × Indica two-line hybrid rice variety bred by Zhongzao 35. The variety application was submitted by China Rice Research Institute and approved at the second meeting of the Third National Crop Variety Approval Committee on October 18, 2013. The approval number is Guoshen Rice 2013001.

Characteristics:

Indica two-line hybrid rice varieties. The whole growth period of double cropping early rice in the middle and lower reaches of the Yangtze River is 1.7 days longer than that of the control plant Liangyou 819 (the whole growth period of plant Liangyou 819 is 105.4 days). The plant height is 89.0 cm, the spike length is 18.5 cm, the effective spikes per mu are 220000, the total grains per spike are 111.9, the seed setting rate is 82.6%, and the 1000 grain weight is 26.1 g. Resistance: the comprehensive index of rice blast was 3.4, and the loss rate of ear blast was the highest at 5; Grade 7 of bacterial leaf blight, grade 7 of brown planthopper and grade 7 of white backed planthopper; Moderately susceptible to rice blast, bacterial leaf blight, brown rice hopper and white backed planthopper. Main indexes of rice quality: length width ratio 2.5, chalkiness 17.8%, gel consistency 70 mm, amylose content 25.6%.

Output performance:

In 2010, he participated in the regional test of early medium maturity group of early indica rice, and the average yield per mu was 7.2% higher than that of the control plant Liangyou 819. In 2011, the average yield per mu was 6.3% higher than that of the control plant Liangyou 819; The average yield of the regional test in two years was 6.7% higher than that of Zhuliangyou 819. In the production test in 2012, the average yield per mu was 7.5% higher than that of Zhuliangyou 819.

Key points of cultivation technology:

1. Sow in late March, with the seeding amount of 15kg per mu in the seedling field, and cultivate strong seedlings.

2. The seedling age is 25-30 days, and the planting density is 17 cm × 20 cm, 80000 to 100000 basic seedlings per mu.

3. Apply sufficient base fertilizer, topdressing early and ear fertilizer skillfully.

4. During transplanting and seedling throwing, the water layer in the field shall be kept at 1-2 cm. During the tillering stage, dry and wet conditions shall be alternated to promote tillering. When the total number of seedlings per mu reaches 230000 to 250000, the seedlings shall fall into the water and be dried in the field. During the booting stage, it is mainly wet. During the heading stage, it is necessary to keep the water in the field. During the filling stage, it is necessary to keep the seeds dry and wet to maintain the vitality of the root system and prevent premature water loss.

5. Soak seeds with strong chlorine to prevent the occurrence of bakanae, and focus on the prevention and control of rice blast, borer, sheath blight and other diseases and pests.
