In order to maintain the high yield of Atractylodes
Atractylodes macrocephala as a kind of Chinese herbal medicine with higher economic value has been planted by more and more people. However, due to the uneven levels of planting and management, the economic benefits of growers differ greatly. In particular, the initial planting of Atractylodes macrocephala was not accurately controlled by its growth habits and pest control, often resulting in a large number of dead seedlings in the early stage of Atractylodes macrocephalae, and the benefits were low, and some of them were even lost. After several years of planting, my greatest experience is that: In order to have a high yield of Atractylodes, it is most important to maintain seedlings early.
First, to strengthen the seedlings and seek ways to promote the Atractylodes Miao Miao Zhuang, can greatly enhance the resistance of Atractylodes disease, and promote seedlings is the basis for high yield of Atractylodes. The specific method is a reasonable cultivator. After the Atractylodes seedlings emerge, they must carry out two cultivators. When cultivating the cultivars, they should master the principle of “head 锄 , , 锄 锄 锄 锄 锄 锄 , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,. . The second is the spraying of foliar fertilizer. If the white seedlings are thin and weak, 15 kg of water can be used for 15 ml of Biora plus 25 g of monopotassium dihydrogen phosphate. The whole field sprays. If the seedling leaves have a small yellow color, 15 kg of water can be used for Rui Peileu 10g. Ruipei zinc 5 grams, spraying all fields.
Second, the control of water fertilizer because Atractylodes resistant to drought, fear of waterlogging, so as much as possible to control the water, especially at the seedling stage, not less than a waterless resort, but at the same time, watering per acre Chong Shi Rui Miao Qing 200 ml plus grain Surplus 1.5 kg to prevent seedling disease.
3. Diseases and pests control There are three major diseases that cause dead seedlings in Atractylodes macrocephala, including blight, root rot, and damping-off, of which blight is the most serious and most harmful. Blight, also known as "Rotten Stem," is more severe on rainy days. The base of the victim's stem is dark brown, and then shrinks and sinks, causing the seedlings to collapse and die. Root rot occurs at the root, and the main root rots, resulting in seedling death. The damping-off disease and the incidence of blight were the same. They were all at the base of the stem. After the onset, they quickly fell down, but the upper part was normal. Water control is the first step to control, and the less humidity in the field, the lighter the incidence.
In the early stage of disease, 15 kg of water were used to control the bacterial wilt and root rot. Bupa disease was treated with Propolis 20 ml spray with 15 kg water. It should be noted that when spraying, the liquid should be allowed to flow to the rhizomes of Atractylodes macrocephala.
Atractylodes major pests include aphids, spotted lizards, and ground tigers. Aphids and planthoppers are used for prevention and control of gold for good years, and Liriomyza formosanus is treated with avermectin plus enemy kill. Prevention of ground tigers can be sprayed with Baishu before the evening around the roots of Atractylodes.
