Soaking treatment before cuttings of Phalaenopsis seedlings is an important step. A detailed comparison has been made. The survival rate of fast-growing Phyllostachys vulgaris seedlings after immersion treatment is 20% to 40% higher than that of non-immersion. The soaking time of paulownia seeds is also particular. After long-term comparison and observation, the survival rate of soaking for 70-80 hours is much higher than that of the small stalks of paulownia soaking for 24 hours or 160 hours.
After powdery mildew infects the fast-growing Phyllanthus vulgaris, it lurks in the tree and usually begins to onset from May to June each year. At the initial stage of the disease, small white powdery spots appear on the front or back of the leaves, and then gradually expand, causing the tender leaves to shrink and curl up. The new shoots are twisted and shrunk, which affects the normal growth of the tree. When the disease is severe, yellow-white small dots are formed in the white powder layer, and then gradually turn into yellow-brown or black-brown, causing the leaves of Farton to wither and fall off early.
Before planting the young plantlets of Phyllostachys vulgaris, combine tillage and land preparation, and apply 6 to 7 cubic meters of decomposed manure, compost and soil miscellaneous manure per acre. Top dressing should be carried out during the vigorous growth stage of the plantlets.
The main fertilizer is quick-acting fertilizer, especially during the rainy period from June to August, it should be applied once a month. Because the organic fertilizer has a long fertilizer effect, it can continuously supply nutrients to the Phyllostachys vulgaris seedlings during the entire growth period, which promotes the accelerated growth of the Phyllanthus vulgaris seedlings.
