Red bayberry needs ploughing, weeding and scientific fertilization after fruit picking.

The planting method of red bayberry is very important. in addition, we should do a good job in the management of postharvest bayberry to overcome the various phenomena that can easily lead to diseases in the coming year, and lay a foundation for high and stable yield in the coming year. Among them, the step of ploughing and weeding is indispensable. Apart from this step, what else should we pay attention to?

1. Attention should be paid to ploughing and weeding after bayberry fruit picking.

When red bayberry enters the harvest time, ploughing and weeding are critical, combined with fertilization to carry out ploughing and weeding at a depth of 10 to 20 centimeters, and then cover the tree plate with weeds. Mid-tillage can change the soil consolidation caused by rain and pedal under the tree crown, enhance the water storage and fertilizer conservation capacity of the soil, and improve the resistance of trees to drought, which is very beneficial to flower bud differentiation. Soil cultivation and root protection can be carried out if possible.

II. Key points of fertilization after bayberry fruit harvest

1. Apply the "tonifying" fertilizer after fruit harvest.

Because red bayberry consumes a lot of nutrients during fruiting, applying "tonifying" fertilizer after fruit harvest is of great significance to promote the restoration of tree potential, promote summer shoots, improve and promote flower bud differentiation. It can be said that this fertilizer is the most important fertilizer for the whole year, and it is also the basic fertilizer for the whole year, which is generally required to be carried out within one month after fruit harvest. The fertilizer used in this fertilization should be mixed with quick-acting fertilizer and organic fertilizer such as cake fertilizer and manure. Reference fertilization method: take an adult tree with a yield of 30kg to 50kg of bayberry as an example, 1.5 kg of potassium sulfate compound fertilizer, 0.5 kg of superphosphate or lime, 3.5 kg of cake fertilizer or manure.

2. Apply good fertilizer to promote shoot.

When red bayberry shoots new shoots in August and September of the lunar calendar, flower buds also grow in the axils of leaves, that is to say, the fruit of red bayberry will mature with the growth of new shoots. Therefore, red bayberry needs to apply shoot-promoting fertilizer in June and July of the lunar calendar, and this fertilizer is mainly applied with quick-acting chemical fertilizer. Reference fertilization method: take an adult tree with an annual output of 30kg to 50kg of bayberry as an example, applying 0.5 kg of urea and 0.5 kg of potassium sulfate per plant.

3. Apply lime to regulate pH value.

This is a problem that is often overlooked by fruit growers. Due to the high acidity and low pH value of red soil in the southern mountains, it not only affects the root growth of red bayberry, but also affects the absorption of water-soluble phosphorus. The application of lime can not only reduce soil acidity and increase soil pH value, but also provide a large amount of calcium to promote the root development of red bayberry, accelerate the mycorrhizal growth and improve the nitrogen fixation activity of mycorrhiza, so as to enrich the red bayberry tree and improve the fruit quality. Topdressing lime can be applied in conjunction with other fertilizers in the first fertilization after fruit harvest, or in the crown in winter, and can play a role in insect and disease prevention. The application of lime depends on the type of soil, generally no more than 0.5 kg per plant.

4. fruit tree taboo excessive application of phosphate fertilizer

Due to the role of phosphorus in promoting mitosis, excessive application of phosphate fertilizer will produce many problems, such as more fruit, hard core, less fruit juice, dry and astringent, which seriously affect the quality and edible value of fresh fruit. Of course, it is necessary to apply phosphate fertilizer, otherwise it will lead to too little flower bud formation and affect the annual yield in the coming year. In general, the ratio of nitrogen, phosphorus and potassium should be 6:3:1 or 1porpor0.3. 4.

Warm reminder: as chloride ion will cause damage to the root system of red bayberry, it is not suitable to apply chlorine fertilizers such as potassium chloride and ammonium chloride, it is best to use potassium sulfate instead of potassium chloride.
