“Zhaozhong No.6†is a precocious and fine glutinous rice variety promoted by the “One Township One Product†project in Xihe Town, Dapu County. Its main management techniques for young trees are as follows:
1. Reasonable fertilization
The “early bell six†can be pumped for 3 to 4 times a year for 1 year. Ye Mao has a large number of flowers and needs a large amount of fertilizer. Reasonable fertilization is the basis for high yield and stable yield.
The fertilization of young trees is mainly carried out by rapidly expanding the crown. During the growing period of Lichi shoots from February to October, fertilization is applied once every two months, especially before each shoot shoot, with available nitrogen fertilizer as the main ingredient, and with decomposed organic fertilizer; from November to January of next year One overwintering fertilizer is dominated by organic fertilizers. The annual fertilization is about 6 times, so as to promote the growth of new shoots, which is full and healthy, and lays the foundation for stable production.
2. timely shaping pruning
According to the prominent growth characteristics of the center of the banyan tree, the trunk of the trunk is mainly cultivated in production. The method of shaping the young eucalyptus is: after the planting, the seedlings should not be cut and dried. In the spring, the top buds will continue to grow naturally and become the center trunk. The three branches that grow robustly and are distributed uniformly between 30 and 60 cm in height are selected. Cultivate and become the first main branch, erase the remaining branches.
3. Disease prevention and treatment
The common diseases are gray leaf spot, spot disease, and angular spot disease. The peak period of disease is from April to July every year. It mainly damages the leaves of eucalyptus trees. When it is severe, it causes defoliation, decline of tree vigor, and decline of new shoots, resulting in a decline in yield. .
Symptoms: (1) Gray spot disease: The affected leaves initially showed light brown round lesions, then turned grayish white, with dry epidermis, and healed into many irregular shape lesions with thick and thin black dots. (2) Scab: The lesions are reddish-brown dots at the beginning of the lesions, and then gradually expand into a nearly circular shape with a grayish-yellow central area and finer and denser black dots on the late lesions; (3) Keratopathy : At the beginning of the onset of the leaves, brown dots were found. Afterwards, they were expanded into veins and bounded as polygonal lesions. Most of the lesions healed into irregular large lesions and black moldy dots grew on the latter lesions.
Prevention measures: (1) Strengthen management: increase organic fertilizers, increase tree vigor, increase tree disease resistance, and do preventive measures against waterlogging and drainage during the rainy season to reduce humidity and reduce the spread and spread of germs. (2) Chemical control: After each new shoot has grown and a new leaf has been grown, spray control. Use 50% thiophanate-methyl WP 500 times or 70% sorbate MnZn WP 500 times, 50% more. Zotin 800 times liquid and other pesticide spray. Prohibit the use of omethoate, methamidophos, trichlorfon, dichlorvos, and highly toxic pesticides to avoid injury.
