Published: 2024-11-24 Author: mysheen
Last Updated: 2024/11/24, Variety characteristics: the whole growth period of this variety is 107-108 days, which is about one day earlier than that of Zhejiang 852, so it is suitable for light cultivation. The tiller is medium, the panicle shape is large, the total grain number per panicle is about 110, the full grain is about 90, the seed setting rate is 80-85%, and the 1000-grain weight is 22.5-23.0 g. The cold tolerance of seedling stage is good, it is not easy to rot seedling, the rate of mature seedling is high, and the elasticity of seedling age is medium. More resistant to fertilizer and lodging. Medium resistance to rice blast and bacterial blight, good color change in the later stage, green stalk yellow ripe. The quality of rice is excellent, according to the quality Inspection Center of Rice and products of the Ministry of Agriculture.

The rice is of high quality. According to the determination of the Rice and Product quality testing Center of the Ministry of Agriculture, the seven main quality indexes of this variety, such as milled rice rate and straight-chain flour content, reach the second-class standard of edible high-quality rice issued by the Ministry. The provincial "9410" cooperation group organized many times and ate more food in the province. The score of Jiayu 948 was 6.2, which was significantly better than that of Xieyou 45. The rice is palatable and tastes good.

Main cultivation techniques:

The main results are as follows: 1. Cultivate strong seedlings of appropriate age. The seedling age is controlled within 30 days, the transplanting leaf age is not more than 5.5 leaves, the sowing amount per mu of seedling field is not more than 40 kg, and the ratio of Honda to seedling is about 5.5.

2. Few books should be planted in close proximity. Transplanting 2.8-30000 clumps per mu, the basic seedlings reached 12.0-150000 / mu.

3. Rational fertilization. Apply sufficient base fertilizer, mainly organic fertilizer, early adequate application of seedling fertilizer, combined with phosphorus and potassium fertilizer. The total amount of fertilizer used is controlled at 50-55 piculs / mu of standard fertilizer.

4. Scientific water slurry management. Early application of early management to promote early onset, control of the highest seedlings in the middle stage, 40-500000 / mu should be controlled, water cut-off should be prevented too early in the later stage, and attention should be paid to insect control of disease (mainly sheath blight).
