The latest course of lotus cultivation techniques and methods

Lianwu originated in India, also known as Yangpu peach, mainly planted in tropical areas, such as Hainan, Taiwan, Guangdong, there are mainly green and red, the fruit contains a variety of nutrients, is a tree-type fruit tree. Arbor fruit trees, the key part of the cultivation technology is some management techniques in the later stage, because it takes many years to grow after planting, so the management time is long, the specific content of cultivation can continue to read the following articles.

I. Propagation methods

The common method is cutting, the cutting is easy to survive, the seedling is very fast, in autumn, take one-year-old branches, about 10 centimeters long, cutting in the sand seedbed, always moisturizing and shading, about a month later will take root. Sowing should be carried out in spring. After nursery bed nursery, select high-quality seedlings. Dig holes about 1 meter wide and 1 meter deep. After applying sufficient basic fertilizer, plant about 400 plants per mu on flat land and 450 plants on sloping land. Striping, carried out in summer, select thick branches, peel around the base of 2 cm, cover with wet soil, grow roots, cut off and plant.

Second, promoting flowers

It needs to promote flowers several times a year, soak it in water for one and a half months after summer harvest, and damage the trunk, beating the phloem of the trunk until it is loose. You can pull the branches apart and keep them drooping, which can accumulate some nutrients, supply flowering and inhibit the growth of branches. in fact, they can also twist, ring-cut and so on.

3. Pruning

Keep most of the spring shoots, remove a few, remove some bad buds before sprouting, renew the branches of the fruit tree in summer, leave some strong summer shoots, and remove the rest, so as not to consume nutrition. In addition, the adult trees that will bear fruit for the first time should cultivate the fruiting branch group. Young trees need to set the stem, and then leave branches to cultivate the shape of the tree. Aging trees should be renewed and rejuvenated, generally cutting off some old branches, promoting new branches, and root system renewal in turn, first cutting off part of the root system, and then cutting off the other side in the coming year.

IV. Water and fertilizer

Lianwu likes fertilizer, it is necessary to control nitrogen fertilizer in the early stage, apply more phosphorus and potassium fertilizer, do not apply nitrogen fertilizer at flowering stage, apply more phosphorus and potassium fertilizer after flowering, do not water at flowering stage, and keep moisture at other times, applying 1500 jin per mu of adult tree base fertilizer. The basal fertilizer of young trees is 1000 jin per mu, and that of aging trees is 600jin per mu, which is used twice, once in autumn and once before spring. In the result period, 50 jin of nitrogen fertilizer and 30 jin of phosphate fertilizer were sprayed with nitrogen and phosphorus.

5. Diseases and insects

Anthracnose, the main disease, infected fruits and leaves, can be sprayed with 56% Tekedo wettable powder or 43% Chunramycin wettable powder, you can choose a variety of agents, mainly some fungicides. Usually spray after pruning diseased branches and fruits. The main insect pest, the beetle, shook the tree directly, killed by false death on the ground, trapped and killed with a mixture of sweet and sour liquid, and sprayed 1500 times of imidacloprid wettable powder.

Lotus cultivation techniques are mainly the methods of planting and raising seedlings and some management of promoting flowers and fruiting, and we need to pay attention to the regulation and supplement of nutrition and water. It is worth noting that there are various diseases and insect pests in the orchard, especially when it is hot and rainy in summer.
