On the morning of June 9, good news came from the seed production paddy fields of Jiangsu Hongqi Seed Industry Co., Ltd. After 4 years of experimental demonstration and painstaking research, the company's production team successfully implemented the hybrid rice seed production male parent long seedling-age machine transplantation operation. After this technical difficulty was overcome, it marked the realization of the full mechanization of the hybrid rice seed production process in Taizhou.

　　At the Hongqi Seed Industry's 10,000-mu rice and wheat demonstration planting base, two rice transplanters shuttled back and forth with the "Taiyou 950" parent blanket seedlings. Behind them, rows of sturdy male seedlings were fixed in rows and holes, and planted into the fields at high speed. However, before this, due to objective conditions such as plant height and seedling age, the male parent seedlings of hybrid rice could not be transplanted mechanically. Instead, they could only be planted manually, which was time-consuming and laborious. The planting quality was uneven and pollinated the rice flowers. Cause a certain impact.

　　"Under normal circumstances, the ratio of father to female parent is 1:6 for rice seed breeding, and the male parent should be planted about 25 days earlier than the female parent. Only when the male parent seedling meets the height of 12-18 cm, the leaf 6-7 leaves Only with 3-4 leaves of the female parent leaf can the machine transplanting operation be realized.” According to Professor Huo Zhongyang of Yangzhou University, to meet the objective conditions of machine transplanting, the technical essentials such as the amount of seeding in the early stage, the management of water slurry and chemical control in the later stage must be mastered. .

　　Right now, the successful application of this technology, not only to solve the Hybrid Rice Seed Production problems during labor, and this labor saving, increase productivity, avoid planting seedling age male super, lack of planting density and weak, transplanting seedlings planted when the temperature injuries, leading to the parents of the flowering period does not meet a series of problems. "Effective increased paternal planting density, improve maternal outcrossing rate, boost rice seed production to achieve full mechanization." Seed Industry Co., Ltd., deputy general manager of Jiangsu red flag Sun Jianrong said confidently.
