Experts suggest: "enlarge the demonstration to promote the early change of early death" noisy varieties

In the near future, the "Zhu Zai Zao Zai Yu" demonstrative field planted on the 200-mu "Lian Zao Zao Zao Yu" planted in Luozhe Town, Menghai County, Xishuangbanna Dai Autonomous Prefecture, Yunnan Province was selected to enter the yellow ripening stage. After the agricultural science and technology department measures the output, the theoretical yield is 20% to 40% higher than the locally grown early-season cultivars. Experts suggest that further expand the demonstration and promotion, give full play to the advantages of solar thermal resources in the hot area, and promote the high yield and high quality development of double-season rice cultivation.

The Xishuangbanna, Dehong and other hot regions in Yunnan Province have the tradition of planting indica rice in two seasons. The Provincial Japonica Hybrid Rice Engineering and Technology Research Center cooperated with the Xishuangbanna State Seed Management Station and the State Agricultural Research Institute and other departments to update the varieties as a breakthrough for the high yield and quality of double-season rice, utilizing the advantages of strong cold tolerance and good palatability of the indica hybrid rice varieties. To carry out the "early repentance early reform" to improve the yield and multiple crop index innovative exploration.

Since 2010, Xishuangbanna Prefecture has introduced more than 20 varieties of japonica rice such as “Noisy” and “Yunshan”. Last year, in the village of Mangnong Village, Yanzhe Town, Menghai County, the plant was planted with "Noisy 35" and the yield per mu reached 584.7 kg. This year, 200 acres of “Noisy 35” planted in the Mannema Village of Mann Village Committee will be incorporated into the high-yield, 100-acre demonstration area. Recent field surveys and production surveys have shown that indica rice hybrids have strong stalks, compact plant types, and high effective panicles and high seed setting rates. The yield per mu is between 699 and 808 kilograms, which is higher than the average per mu yield of adjacent rice in adjacent fields. The demonstrations in the past two years show that "Noisy 35" is strong in stress resistance, moderate in growth period, and of good quality. It is especially suitable for early and late periods of high temperature conditions in ecological conditions, and achieves early sowing and early harvest in middle altitude areas, which is more advantageous than indica rice. Outstanding, can better resolve the contradiction between early rice harvesting and late rice planting.
