Planting technique of Akebia trifoliata

Planting Akebia trifoliata should first select the garden, and then carry on the interplanting cover to prevent water from evaporating too quickly. Fertilize, prune, control diseases and insect pests. Harvest after maturity, preferably when uncracked or microcracked.

I. Garden site selection

Akebia trifoliata fruit is built in a place with convenient transportation as far as possible, which is convenient for management and transportation of products. Soil selection of August melon belongs to shallow root tree species, no main root, lateral root is particularly developed. The acidity and alkalinity of the soil should be slightly acidic to slightly alkaline, and the topsoil should contain more humus. There are waste gas, waste water, waste residue pollution sources of places can not build a garden! In order to meet the green organic food standards.

Clover fruit like light, like calcium, generally choose open, leeward to the sun of sandy loam and medium loam is better, waterlogged land is not suitable, low-lying is not suitable for drainage or narrow gully lack of light is not suitable to build a garden. There should be water nearby. Eli resists drought when it is dry. Loose texture, water conservation, strong fertilizer conservation, good air permeability, thick soil layer planted in August melon fast growth, high yield, good quality, low production cost.

Second, interplanting and covering

Akebia trifoliata has strong drought resistance, but because the root system of young trees has not been fully formed, the amount of absorption is small, and it is not very resistant to drought, fruit growth needs to absorb a lot of water. Interplanting and mulching are effective ways to improve the drought resistance of Akebia trifoliata. Interplanting can obtain early economic benefits of woodland. Generally, between the rows of young trees, legumes, vegetables and melons can be interplanted, and leaves, straw and weeds can be covered on the tree plate. Interplanting and mulching can reduce the surface temperature, prevent water from evaporating too quickly, and increase farmers' income.

III. Fertilization

Cooked pigs, cattle, horses, cake fertilizer 2000kg*667m2, urea (N47.5%) 19kg*667m-2, calcium magnesium phosphorus (P12%) 3.6kg*667m2, potassium sulfate (K50%) 40kg*667m2, mixed with soil and then furrow irrigation.

IV. Shaping and pruning

According to the biological characteristics of Akebia trifoliata and the degree of intensive cultivation, the tree shape of Akebia trifoliata should be dispersed and stratified, and the tree crown should be more natural and happy than the open and low-sized fruit trees.

The purpose of trimming Akebia trifoliata is to maintain the shape of the tree, promote fruit and increase yield. Summer pruning can remove useless sprouting and tapping shoots during the growing period, or peel off too strong new shoots to promote the formation of trees. In winter dormant pruning, the relationship among backbone branches, fruiting branches and long branches should be properly handled, and diseased branches and insect pests should be cut off at the same time.

Fifth, the technology of protecting flowers and fruits

The diseases of Akebia trifoliata are mainly anthracnose, angular spot, round spot and leaf blight, and the pests are Spodoptera litura, tea yellow moth, beetle, dried longicorn beetle, cotton scale, aphid, red spider and so on.

The early flower and fruit drop of Akebia trifoliata can be caused by diseases and insect pests or abnormal climate change. more importantly, the physiological imbalance of Akebia trifoliata itself leads to physiological fruit drop. The first physiological fruit drop is in early June, and the second fruit drop is in July. There are many factors causing physiological fruit drop, mainly due to lack of nutrition, excessive fertilizer and water in the early stage or overpruning, insufficient or drastic change of soil moisture, poor pollination and other factors. Akebia trifoliata flower and fruit protection mainly has the following aspects.

VI. Disease and pest control

Spodoptera litura can make use of the chemotaxis of adults, using black light or sweet and sour solution (sugar: vinegar: water-3:1:6), plus a small amount of trichlorfon stomach poison to trap and kill adults. When the larvae are in the harmful stage, 2000 times of 20% Juma mixture is sprayed.

The second generation of tea yellow moth occurs every year, and the larvae are used as cocoons to spend the winter in the trunk cracks, the trees are damaged after the Akebia trifoliata germinates, and the second generation larvae are harmed from August to September. 3000 times of cypermethrin EC is sprayed on the young larvae.

Beetles use black light to trap and kill adults in muggy weather. Spray 20% methamphetamine EC 3000 times in the evening.

White cotton scale produces 2-4 generations a year, spraying 40-6-omethoate 1000 times or 2.5% deltamethrin 2500 times or 20% chrysanthemum EC 2500 times in May-June or September-October nymph stage. In the adult stage, 40% EC was sprayed 1500 times or is% aldicarb internal absorption granules were applied.

The red spider sprays 5 Baumedu stone sulfur mixture in winter. For the damage period, use so% deltamethrin emulsion 2500 times, or i5% acarine EC 3000 times or 5% nisolone EC 3000 times.

VII. Harvest

After cracking, the fruit is not easy to be harvested, stored and transported, so it is best to harvest when it is not cracked or micro-cracked. The general fruit is ripe from late August to early October and should be harvested in time.
