What are the key points of fertilization techniques for water chestnut species of bayberry?

The origin of chufa species is yuyao, it is the main variety of yuyao bayberry market. Water chestnut kind of bayberry meat is soft and sweet and delicious. The key points of fertilization technology for planting water chestnut are very important. Here is a detailed introduction.

1. Fertilization time

Many fruit growers are used to applying base fertilizer in spring, but the fertilizer at this time has not decomposed, and the newly grown spring shoots and fruits are difficult to absorb, which does not play a role in promoting growth. When fertilizing, we can fertilize properly according to the growth cycle of water chestnut and bayberry. For example, from early October to early November every year is the third peak period of root growth of Chinese chestnut, so basal fertilizer can be applied in October, which can not only provide nutrients for root growth, but also play a role in the growth of buds of Chinese chestnut in the second year.

II. Types and dosage of fertilizer

There are many kinds of fertilizer that can be applied to Chinese chestnut, such as compost, cake fertilizer, animal manure, etc. The fertilizer dosage of water chestnut planting bayberry is generally 10-5kg of common manure or 15-20kg of compost or 1- 2 kg of cake fertilizer per bayberry tree (50kg per plant). A small amount of biological fertilizer can also be added.

III. Fertilization methods

The fertilization methods and dosage of water chestnut species are divided into growth stages, and the fertilization of adult water chestnut species and juvenile water chestnut species are different.

1. Adult chufa species bayberry tree

There are two fertilization methods for adult Chinese chestnut species: one is circular fertilization method, which mainly uses trunk when fertilizing, then digs circular ditch with depth of 10~30 cm according to crown size, and finally covers a thin layer of soil with fertilizer. This method uses more fertilizer.

The second is hole-shaped fertilization method, which takes the trunk of Chinese chestnut as the center, digs 5~6 holes of suitable size and balances with the arc or line around the crown, or digs about 6 radial grooves, 70-80cm long, 30-40cm wide and 30cm deep, and finally fertilizes and covers the soil.

2. juvenile chufa species myrica rubra

Young chufa species of bayberry, growth characteristics are different, generally using plate-shaped fertilization method. It takes the trunk of waxberry as the center, harrows the soil in a disc shape, the size of the fertilizer plate is equivalent to that of the tree crown, the depth is 20-30cm, the mound harrowed is surrounded by the plate, and a layer of soil is covered after fertilization.

IV. Precautions

1. The organic fertilizer applied must be decomposed, otherwise the fertilizer applied not only has no effect on promoting growth, but also may cause diseases and insect pests.

2. Organic fertilizer should not contain pesticides banned by the state, such as carbofuran, etc.

3. The root system of bayberry is very important. Pay attention to the dosage when applying base fertilizer. Too much is easy to hurt the root.

The fertilization method of water chestnut is very important. If the fertilizer selected is not suitable or the fertilization time is not equal, it may cause the disease or wither of water chestnut.
