High-Quality Natural Rice Gold Seeds

Characteristics:

Indica two-line hybrid rice varieties. In the middle and lower reaches of the Yangtze River, the whole growth period of a single season of medium rice was 135.6 days, 1.1 days later than the control Fengliangyou No. 4. The plant height is 128.3 cm, the spike length is 25.0 cm, the effective spikes per mu are 157000, the total grains per spike are 236.2, the seed setting rate is 87.8%, and the 1000 grain weight is 24.3 g. Resistance: the comprehensive indexes of rice blast in two years are 3.2 and 2.5, respectively. The loss rate of ear neck blast is the highest grade, grade 3, white leaf blight grade 7, brown planthopper grade 9, highly susceptible to brown planthopper, susceptible to white leaf blight, moderately resistant to rice blast, and has strong heat resistance at heading stage. Main indicators of rice quality: head rice rate 64.7%, chalkiness 1.8%, amylose content 16.1%, gel consistency 76 mm, alkali digestion value 6.8, length width ratio 3.0, reaching the second level of the standard of "Quality of Edible Rice Varieties" in the agricultural industry.

Key points of cultivation technology:

1. Sow at the right time, sow thinly and evenly, and cultivate strong tillers. The seed consumption per mu of field is 1 kg, and the seed consumption per mu of seedling field is 8-10 kg.
2. Transplant in a timely manner. The seedling age should be controlled within 30 days. The planting density should be 12000 holes per mu, with two seedlings per hole.
3. The total amount of pure nitrogen required for each mu of field is 12-14 kg, and the ratio of nitrogen, phosphorus and potassium fertilizer is 1:0.5:0.7. Apply base fertilizer heavily, tillering fertilizer early, and avoid applying nitrogen fertilizer at a later stage. The irrigation method of "planting seedlings in shallow water, living trees in inch water, tillering in thin water, heading in deep water, and dry, wet and wet in the later stage" shall be adopted, so that the seedlings can be timely dropped into the water and dried in the field to control the seedlings.
4. Pay attention to the timely prevention and control of rice blast, sheath blight, bacterial leaf blight, rice false smut, borer, rice planthopper and other diseases and pests
