How to grow mandarin

Wo orange is a hybrid late-maturing citrus variety, the growth potential of Wo orange is very strong, in the initial stage, the crown will show a natural round head, after the fruit will gradually open. Its fruit is a flat round, the skin is relatively smooth, orange, there are plenty of vitamins, but the cultivation of mandarin is very difficult, careless will cause a large number of difficult to bear fruit. So how do you grow oranges? Let's take a look at it.

1. Land selection and fertilization

If you want to achieve the effect of early results, high yield and bumper harvest, first of all, the choice of orchards is very important. When choosing planting sites, you should choose places with fertile soil, loose soil and deep soil layer. The orchard should be ventilated to the sun, away from noisy areas, and have a good drainage and irrigation system. Before planting, we should sprinkle some farm manure and trace element fertilizers such as calcium, magnesium and phosphorus all over the country, and then cultivate the soil in the middle of the garden, and mix the fertilizer with the soil evenly. After turning the ground, the compartment begins to be made at a distance of 8 meters, and it is most appropriate to make an arc on the side of the box. the maximum planting on each box is no more than four rows, the distance between each row is two meters, and the distance between each plant is about one meter. it can be planted in about a month after soil preparation.

2. Reasonable close planting

If you want to make the mandarin grow well and normally, it is the most important factor to control the planting density properly until the fruit is harvested. However, in order to achieve high yield, it is necessary to use the method of close planting, usually with planned close planting, that is, the planting method of dense planting before and after sparse planting. The planting density in the early stage should be about 2m, and the management should be strengthened, then the fruit should be tested in the second year, and the yield should be increased in the third year. In the fifth year, we can start interlacing, increasing the density to 41m, and then changing the density to 42m in the eighth year, so we don't have to change it.

3. Prophase management

The management of the orchard in the first two years after planting is very important. When the spring shoot of the seedling grows to 5 cm, topdressing is based on quick-acting fertilizer, that is, nitrogen fertilizer, which is applied every half a month, in order to promote the growth rate of new shoots. When the new tip grows to 20 cm, it should be treated with coring in time, in order to promote the differentiation of branches. Try to let it shoot 3-4 times in the first year, so that you can quickly expand the crown, you can use the method of integration of water and fertilizer, mainly phosphorus and potassium fertilizer in September. It is mainly phosphate fertilizer and organic fertilizer in October, and foliar fertilizer and trace elements should be the main fertilizer in the growing season.

4. plastic surgery to promote fruit.

The growth rate of mandarin is very fast, so attention should be paid to the tree culture in the first year after planting. It should be dried immediately after planting seedlings, and the general fixed stem is to leave about 30cm for short cutting, in order to promote branching. After the spring shoots stop growing, the spring shoots of more than 20 cm should be cut properly. In summer, due to the irregular growth of summer shoots, it is necessary to pick the hearts of long branches with 20 centimeters to prevent the excessive growth of long branches. Then, after the summer shoots stop growing, the longer shoots should be cut short, and some potassium dihydrogen phosphate should be sprayed on the leaves to promote the growth of shoots, and then apply appropriate amount of nitrogen fertilizer to promote the germination of new shoots.

The above is a brief introduction to the planting method of Wo mandarin, which is more difficult to grow, and it takes some technology to grow Wo mandarin. If the planting method is incorrect or the management is not in place, it is very difficult for the mandarin to hold on to the fruiting period. Everyone must master its planting technology before planting, and make decisions according to their own conditions and market demand. Don't plant blindly, or it will be meaningless in the end.
