2, citrus planting technology:
Selection and management of planting citrus;
There are many varieties of oranges. People who know something about oranges generally know that there are three or four varieties of oranges, grape orange, sweet orange, lime and red orange. In fact, these varieties are often eaten, indicating that the yield is very good. Secondly, we should choose seeds according to the consumption situation in the market and local conditions, see which kind of oranges have higher consumption and greater competitiveness, and then choose good seeds according to the local environment.
Soil preparation and fertilization of seed orange;
After selecting seeds, soil preparation and base fertilizer treatment are needed. In order to grow oranges well and improve the survival rate of oranges, we need to dig deep into the land first, then dig pits with a depth of 60 cm and a width of 60 cm on the ploughed land, then pour 50 kg of farm manure and 30 kg of ternary compound fertilizer into each pit, cover the fertilizer with a thin layer of soil, and wet the thin soil, and finally we can plant it.
Reasonable close planting of seed orange;
Reasonable close planting is actually a reasonable planning when digging a pit. In fact, oranges are a kind of fruit that likes light. In the process of growing, oranges need sufficient light, and only with sufficient light can they grow and develop. At the same time, it can also increase the output of oranges, so it is very important to plant them reasonably and closely. The most suitable density for citrus growth is about 2 meters between plants and 3 meters between rows. This distance can ensure the illumination, improve the permeability of the site and facilitate the later management.
Fertilizer and water management for planting citrus;
There is a certain gap between fertilization and watering in different growth stages of oranges. For citrus reticulata in seedling stage, fertilization should be applied at least 6 times a year, mainly to promote the growth of citrus reticulata and shorten the growth cycle. Generally, organic decomposed fertilizer and foliar fertilizer are used at the same time. In the fruit-bearing period, orange trees only need to be fertilized four times a year, mainly using organic decomposed fertilizer or farmyard manure combined with foliar fertilizer. Fertilization methods are generally annular furrow application or hole application, so that nutrients can play a maximum role. The orange trees in seedling stage should be watered frequently, and the accumulated water should be drained in time. Water once every half a month after the fruit, and try to water it as little or no as possible in the middle and late stages of fruit growth, because sugar needs to be precipitated. If there is too much water, oranges will taste very light and sweet.
Field management of planting citrus;
Garden management mainly includes weeding, pruning and leaf cutting, thinning flowers and fruits, bagging, pest control and garden cleaning. Weeding is mainly done at seedling stage, generally through intertillage weeding, which can enhance soil permeability and improve fruit tree immunity at the same time. Pruning and leaf cutting are also in progress. The seedling stage is mainly to cut off the messy branches and leaves. In the early stage of fruit, the main purpose is to promote the growth of lateral branches and make them grow horizontally. Therefore, it is necessary to carry out proper shaping, and when the fruit is vigorous, it is mainly to trim the old, weak, sick and residual branches and leaves.
