Wandao 30

Wandao 30 (formerly 88-23) was systematically bred from the variants of late japonica variety Wangcheng Xuanliu in Anqing Institute of Agricultural Sciences, Anhui Province. It was examined and approved by Anhui crop Variety approval Committee in May 1996. After years of experiment and demonstration, it shows high yield, high quality, good plant type, fertilizer resistance, lodging resistance and disease resistance, which is especially suitable for double late cultivation along the Yangtze River.

Characteristic characteristics: plant height 75~85cm, compact plant type, dark green leaves, large opening angle of lower leaves, wide leaves and short flag leaves, which is beneficial to photosynthesis. The stem is stout, fertilizer-resistant and lodging-resistant. Ear length 14.3~15.2cm, grain density, average filled grains per panicle 75.4-80.1, seed setting rate about 80%, 1000-grain weight 24.7~26.Og, medium tillering ability, panicle rate more than 80%, good late ripening phase, not easy to thresh, the whole growth period is 125-130 days. Brown rice rate 83.6%, milled rice rate 75.7%, head rice rate 71.1%, grain length 5.3mm, aspect ratio 2.05, chalkiness rate 3%, chalkiness 0.20%, transparency 1, alkali elimination value 6.8, gel consistency 77.0mm, amylose content 18.9%, protein content 9.8%.

Participated in the late stalk regional trial in Anhui Province from 1991 to 1992, the average yield per 667m2 was 399.6kg, which was 8.0% higher than that of the control Eyi 105. In the production trial of late japonica group in Anhui Province in 1994, the average yield per 667m2 was 362kg, which was 2.6% higher than that of the control.

Region and technology 1. Sow seeds at the right time. The double-late cultivation period is from June 15 to 20, and the sowing amount per 667m2 should not exceed 35kg, and sufficient base fertilizer should be applied to cultivate green and strong seedlings. two。 Timely transplanting and reasonable close planting. The seedling age should be controlled within 40 days, usually double-late cultivation, the transplanting period is the middle and late July, the planting density is 225 ~ 30000 holes per 667m, 8 seedlings per hole, row spacing 17cm, plant spacing 13cm. 3. Scientific fertilizer and water management. This variety has strong fertilizer tolerance, and the total nitrogen per 667m2 is 10kg / 12kg P _ 2O _ 56kg ·K207kg. The base fertilizer is mainly farm manure, which is fertilized according to the length of weeding. After roasting the field, keep it dry and wet in the later stage to mature, prevent the water from being cut off too early in the later stage, and prevent diseases in time.
