In September, the weather gradually turned cold. Because of the condensation of water at night, in the early morning, many dewdrops appeared on the foliage of plants, and Bailu was named after it. At this time, the weather is characterized by large temperature difference between day and night, rapid temperature drop, and increased rain. Experts reminded that during the "Bailu" season, on the one hand, we must pay close attention to the harvesting and turning of the rice, to reduce or avoid the danger of autumn rain; on the other hand, we must also store the water in the rain to meet the agricultural production needs of autumn and winter.
Rice: produced while harvesting
At present, the rice in the Weinan, Jidong deep hill and middle and low mountain areas of Chongqing has gradually matured, and the reclaimed rice in the western Yunnan and central Guizhou has begun to pick up and flower. During this critical period, rice production should focus on rice harvesting and reclaimed rice production.
On the one hand, the southern part of the Weinan, the eastern hills of the eastern part of the country and the middle and low mountain areas should be harvested in time according to the changes in the weather. Especially in paddy fields with relatively good water source conditions, the rice piles should be properly raised during harvesting in order to regenerate the buds to grow seedlings, which can be used as livestock forage.
On the other hand, when about 20% of the regenerated rice ears in the whole field start to head, the pesticides can be sprayed evenly to increase the earing rate and yield of the regenerated rice. In addition, at this time, it is still a season with frequent pests and diseases, and timely prevention and control of aphids and rice planthoppers should be carried out according to predictions.
Autumn potato: seize the opportunity to sow
From late August to early September, it is the sowing date of autumn potatoes. Combined with recent weather conditions, the planting of this autumn potato should be completed by September 15th.
In the selection of varieties, experts suggest that early-type detoxification varieties with high temperature resistance, short dormancy period, early potato and strong antiviral should be selected. Such as: æ¸ potato No. 1, Chuanxi 4, E potato 5 and so on.
In terms of cultivation, rice bran and canola interplanting can be adopted. For farmers who have already harvested paddy fields, experts recommend using straw-covered planting methods to achieve cost savings, increased yield and conservation tillage.
In addition, in the prevention and control of pests and diseases, attention should be paid to the prevention and control of late blight, bacterial wilt, ring rot, viral diseases and aphids and mites.
Vegetables: pay close attention to pests
In mid-September, it is the season when the plastic greenhouses are harvested after the autumn, and it is also the period when the lettuce, the white celery, the celery and other vegetables are planted. During this period, we should pay close attention to the situation of vegetable pests and diseases while doing harvesting and planting work.
At this stage, the main pests of vegetables are Spodoptera litura, Plutella xylostella, Pieris rapae, etc., and can be comprehensively controlled by various methods such as biology, physics and chemistry. In addition, after the white dew, it is also the time to plant fast-growing leafy vegetables, such as Shanghai green, coriander, oily wheat, etc., and the sowing of overwintering tomatoes, eggplants, peppers, and sweet peppers.

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.
