Because of the difference in temperature between the north and the south, rice harvesting is different in the morning and evening. What time can rice be harvested? Let's introduce Xiaobian to everyone about the harvest time of rice. Rice harvest time North China is a single season rice. One season of rice must be planted before the Qingming period, and transplanted at the end of April and early May (if conditions permit, it can also be transplanted in the valley rain). The northeastern region of the north is early-maturing single-season rice. The sowing time is around April. In the northern double-season rice, the first season of rice is 104 days, and the second season is 87 days. Usually early varieties. Avoid the winter. Planting double-season rice in the north must cultivate special early-maturing varieties. The first season of rice cultivation from the middle of the solar calendar in April, can be mature harvest in early August, about 104 days. In the second season, rice is generally transplanted while harvesting. I harvested it without landing. In the south, the middle and lower reaches of the Yangtze River are taken as an example. Early rice is planted in mid-April, transplanted in early May, harvested in late July, and immediately planted in late rice (called double grab). Generally, it must be completed before the beginning of autumn, and late rice harvest in late October-November. . The above is the harvest time of rice introduced by Xiaobian. Because of the difference in temperature and moisture every year, the harvest time may be different. I hope that the Xiaobian article will help everyone.

The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
