How to control the "early panicle" of rice?
The Yangtze River and Huaihe River basins have continued to suffer from drought and little rain this year, which has seriously affected agricultural production. From July to August, the phenomenon of early panicle appeared in the rice planting areas north of the Yangtze River and in the Huaihe River basin. The performance in the field showed that the early heading of each hole was 2mur3 ears, which was different from the late tillering for more than 7-10 days, obviously showing "two ear" or "three ear". To make up for the loss of field production caused by "early spike" as soon as possible, the following analyzes the causes of early spike and puts forward rescue measures. The length of rice seedling age is closely related to the phenomenon of early panicle.

How to prolong the rice seedling age and prepare for drought resistance and rain planting?
In normal years, the seedling age of machine transplanting is about 30 days, that of throwing seedlings is about 40 days, and that of water raising seedlings is about 50 days. If the planting water comes late, it will be faced with extending the seedling age to more than 60 days in order to wait for the seedlings to be planted in water. First, sparse sowing to cultivate long-aged and strong seedlings. That is to say, by expanding the area of seedling bed, reducing the sowing amount per square meter and prolonging the lag tillering period of seedlings, the age elasticity of early sowing seedlings can be effectively increased, the seedling quality can be improved, and the per unit yield can be improved. it can also solve the contradiction of anhydrous transplanting in the early stage.

How to prevent early bolting of Angelica sinensis
Angelica is native to alpine mountain area and is a plant with low temperature and long sunshine. In ontogeny, vegetative growth to reproductive growth goes through two stages: vernalization stage (low temperature of 0 ℃) and light stage (long sunshine for more than 12 hours). Therefore, artificial cultivation requires growing seedlings in the first year, harvesting roots for medicine in the second year, and bolting and flowering and fruiting in the third year. However, in production practice, Angelica often bolts and blossoms in June to July in the second year of cultivation, and the bolting rate in normal years is 10%.
