Young trees should be given quick-acting fertilizers ⟦4 <p>Bayberry is a famous characteristic fruit tree of our country, mainly distributed in various places south of the Yangtze River basin, and the latest high-yield techniques have also been widely popularized.</p><p></p><p>1. Fertilizer and water management: In the current year, annual vegetables or green manure can be intercropped in the woodland to improve soil fertility. Young trees should be given quick-acting fertilizers as the main application, with nitrogen, phosphorus, and potassium applied in combination. Adult trees are topdressed twice a year: the first time in late winter and early spring before bud break and shoot emergence, and the second time after fruit harvest, accounting for 50%—55% of the annual fertilizer application. In addition, work such as soil improvement and draining waterlogged areas should be done well to ensure the high quality and high yield of bayberry.</p><p>2. Shaping and pruning: The tree form of bayberry is mainly the natural round-headed shape. Pruning of young trees is mainly for trunk determination and shaping, cultivating an early-fruiting and high-yielding tree body. Generally, a “one trunk and three main branches” natural open-center canopy is used. Pruning of adult trees is mainly to cultivate a high-yielding population structure, regulate the relationship between growth and fruiting, and promote sustained, high-quality, high yield.</p><p>3. Prevention and control of alternate bearing: Bayberry is a typical fruit tree with alternate bearing, regularly fruiting in alternate years. Therefore, overcoming alternate bearing is an important project in bayberry production, and technical measures such as girdling to suppress shoots and promote flowering and fruit retention, and flower and fruit thinning, can be applied for regulation. 1. Girdling to suppress shoots, promote flowering, and retain fruit: The traditional measure for controlling shoots, promoting flowering, and retaining fruit is ring barking or the use of chemical hormones. This method can achieve good short-term benefits, but it causes great harm to tree vigor, and in severe cases can lead to tree death. At present, the widely applied technique is girdling and applying the pollution-free cationic activator “Flower Promoter No. 2”, which controls shoots, promotes flowering, increases the fruit-setting rate, and can eradicate alternate bearing. 2. Large branch pruning: For adult bayberry trees left to grow freely, use the methods of “cutting high branches and controlling the canopy” and “removing inner branches and opening skylights” on the trunk and main branches. For newly planted young trees, the method of “first letting grow, then pruning” can be implemented, that is, allowing free growth in the first year, and gradually adjusting to a dwarfed and open tree form after the 4th year when fruiting begins. 3. Scientific fertilization: More potassium fertilizer should be applied, once a year. Less phosphorus fertilizer should be applied, because too much phosphorus fertilizer often causes many fruits, small size, and poor quality, aggravating the alternate bearing phenomenon. Nitrogen fertilizer should be applied appropriately to promote the expansion of young fruits. Young trees should be appropriately given chemical fertilizers, while adult trees should mainly be given farmyard manure.</p><p>4. Pest and disease control: Bayberry has strong stress resistance and relatively few pests and diseases. The main insect pests include white peach scale, leaf roller moths, and bagworm pests. The main diseases include brown spot disease and crown gall disease. Control methods: 1. Chemical control: For crown gall disease, after rain in spring and autumn, first use a sharp knife to cut off the disease tumors, then apply “Tree Guard General” emulsion to the wounds, so that the disease spots quickly dry up and fall off, eliminating the source of infection; for brown spot disease, in the early stage of disease occurrence, use 50% carbendazim 500—600 times solution or 70% thiophanate-methyl 800 times solution or 65% zineb 600 times solution + “New High Lipid Film”, spray the canopy once every 7—10 days, for 2—3 consecutive sprays. 2. Strengthen cultivation management to enhance tree vigor; promptly prune diseased branches and dead branches, and after pruning, promptly apply “Wound Healing and Antiseptic Film” to protect the wounds; 3. Do a good job of winter orchard cleaning, remove fallen leaves and weeds, burn them in a centralized manner, and then spray the whole orchard with “Tree Guard General” 100 times solution for sterilization and disinfection.</p>

Detailed Explanation of Key Points for Spring Sowing Cultivation Techniques of Isatis Root
Currently, the Chinese medicinal herb Isatis root is well regarded in the market. The spring sowing season for Isatis root is approaching, so how is Isatis root cultivated in spring? 1. Land selection and preparation. Isatis root is a deep-rooted plant, with a main root that can reach 40-50 cm in length, so fertile sandy soil with deep soil layers and good drainage should be selected for planting. Before sowing, plow the land deeply 20-30 cm; sandy land can be plowed slightly shallower. Apply sufficient base fertilizer, mainly farmyard manure, then break up the clods and rake level to make beds. In the south, high beds are mainly used to facilitate drainage. Generally, the bed width is 1.5-2 m and the height is about 20 cm. 2. Sowing. Isatis root should be sown in March to April. When sowing, first draw shallow furrows about 2 cm deep on the bed surface at a row spacing of 20-25 cm, then evenly scatter the seeds into the furrows, cover with about 1 cm of soil, press lightly, and water appropriately in dry conditions. When the temperature is suitable, seedlings can emerge 7-10 days after sowing. The seeding rate per mu is 1.5-2 kg. 3. Field management. When the seedlings are 7-10 cm tall, thin them in time in combination with cultivating and weeding, and finally set the plants at a spacing of 6-8 cm. After setting the plants, according to the plant growth condition, appropriately apply one additional application of human excrement and urine or chemical fertilizer. In plain areas with abundant water or in rainy seasons, deep ditches should be added around the field to facilitate timely drainage and avoid root rot. If hot and dry weather occurs during the dog days, water in the early morning and evening, and be sure not to water under direct sunlight. 4. Harvesting and processing. For spring-sown Isatis root, the leaves can be harvested 2-3 times. The first time is in mid-June, when the seedlings are 20 cm tall, leaving stubble of 2-3 cm to encourage new leaf growth; the second time is in late August. It is not suitable to harvest during the hot dog days to avoid causing death of large patches. The harvested leaves are sun-dried and become the medicinal Daqingye. Those with large leaves, few broken pieces, cleanliness, dark green color, and no musty smell are best. Isatis root should be dug before the onset of winter on a sunny day. When digging, be sure to dig deep to prevent breaking the roots. After lifting from the soil, remove all soil, stems, and leaves, spread out to dry until 70-80 percent dry, tie into small bundles, then sun-dry further and they can be taken to the market to sell.
