Autumn Astragalus cultivation experience

The temperature in autumn is moderate, the appetite of the yellow peony grows sharply, and the growth rate is also greatly accelerated. Therefore, autumn is the golden season of astragalus cultivation. The autumn referred here refers to the temperature range of 28 to 30 degrees from August to November. The climate at this stage is very close to the spring, but the temperature tends to be opposite to that of spring, and there is also a difference between the spring temperature and the dryness; therefore, the management of the spring is more and more smooth; the management of the autumn is more and more nervous. Tests have shown that, in August and September, the average weight of each scutellariae rose to 88.3 g. The focus of the fall management is twofold.
1, the feeding of food. When the temperature dropped to about 28 degrees, the jaundice was extremely active and the amount of swallowing was also greatly increased. When the temperature dropped to about 20 degrees, the food intake was greater and the feed coefficient increased. When it continues to fall to about 18 degrees, there is a significant decrease in food intake, and the feed coefficient is also large.
2, Dianchi thermal insulation measures. The so-called insulation, on the one hand is the use of the ground temperature rise characteristics, the heat lost in the air is relatively stable; on the one hand is to absorb solar energy, and relatively stable. This measure is achieved by using a new double-layer greenhouse made of a non-drip plastic film to cover the Dianchi Lake. In the natural state of the greenhouse, the humidity inside the greenhouse can generally be increased by 5 degrees compared with the greenhouse.
