Characteristics and cultivation points of High quality Zhongjing Zhendao No.1

Zhendao No. 1 (formerly known as 7038) was cultivated as medium japonica single-cropping rice in northern Jiangsu, and the whole growth period was 140-145 days. The whole growth period of post-cropping rice cultivated along the Yangtze River and southern Jiangsu is 125-130 days. The seed setting rate of this variety is more than 90%, and the 1000-grain weight is 25026g. Plant height 100~105cm for single cropping rice and plant height 85~90cm for post-cropping rice. The rate of finishing rice is 70.39%, and the palatability is good. Medium resistance to sheath blight. The main points of cultivation are as follows: (1) to cultivate in a single season and sow seeds in southern Jiangsu in late May. The post-cropping rice was cultivated along the Yangtze River and in southern Jiangsu and sown from June 20 to 25. (2) the amount of seed used per mu in the seedling field should not exceed 30kg, and the seedling age should be 30-35 days. The seedling age of late stubble in later season should not exceed 40 days. (3) cultivated as single cropping rice with 10 ~ 120000 basic seedlings per mu. For post-cropping rice cultivation, more than 30, 000 holes per mu and 18-200000 seedlings were planted. (4) for single cropping rice cultivation, 12.5kg pure nitrogen is needed for 500kg yield per mu. The amount of fertilizer used in the early stage accounted for about 75% of the total amount of fertilizer, and controlled the use of fertilizer in the middle stage (10-12 leaves). In the cultivation of post-cropping rice, the fields with 400kg yield per mu need to apply pure nitrogen about 10kg. Apply sufficient base fertilizer and early heavy tiller fertilizer. In the later stage, the shallow water was frequently irrigated. (5) do a good job in the prevention and control of diseases, pests and weeds.
