Last Updated: 2024/11/21, Huayou 5, a new japonica hybrid rice combination, is a new combination with high quality, high yield, multi-resistance and early maturity, which is cultivated by Liaoning Academy of Agricultural Sciences. The yield comparison test was completed from 1997 to 1998, and entered the regional trial of hybrid rice in Liaoning Province in 1999. The yield of the comparative experiment from 1997 to 1998 was 574.8-698.1 kg per mu, which was 11.1-27.4% higher than that of the control Liaojing 454Mei17. 1. growth characteristics the growth period of the combination is 155 days and the plant height is 10.

I. Fertility characteristics

The growth period of the combination is 155days, plant height 105CM, effective panicles per mu 198000 ears, tillers 10.8, panicle length 24.4CM, grains per panicle 112.4, seed setting rate 78.5%, 1000-grain weight 27g. It is an excellent combination with good comprehensive resistance, large ear, high yield potential, good rice quality and strong palatability.

Second, the main points of cultivation

1) sparse planting and sparse planting: 150g dry seeds per square meter in seedling field, and the optimum planting density of Honda is (129.9) × 5 inch, ensuring 200000 ears per mu.

2) Fertilizer and water management: 40% base fertilizer, applied in the whole layer before transplanting rice seedlings; 25% tiller fertilizer, applied around June 10; 20% continuous fertilizer, applied around June 20; ear fertilizer, 15%, applied around July 15-20. It is best to apply 1000 kilograms of agricultural fertilizer per mu. The ratio of N, P and K is 1: 1, 0.5: 1.

3) soak the seeds with evil Miaoning and soaking seed spirit.

3. Areas suitable for planting

The combination belongs to mid-early maturity and is suitable for planting in the central and northern regions such as Tieling and Shenyang.
