The conventional management of Hei Hu is similar to that of grapes, but it is more extensive and has fewer pests and diseases. Need to stand up and climb In order to ensure stable and high yield, it is best to carry out artificial pollination at flowering stage. According to the plant size, flowers and fruits should be thinned to ensure the quality of fruits. Toad has many fibrous roots and shallow distribution, so fertilization should not be too deep. Weakly acidic sandy loam is most suitable for planting, and the soil is often kept moist.
1, garden selection. Black tiger is not strict about soil. Peach, plum, jujube, persimmon, pear, apple, grape and loquat can be planted in general soil, but acidic sandy soil is the most suitable.
2. Training method and time. Black tiger is a vine, which can be cultivated in scaffolding, hedges or potted plants. Pergola can plant about 120 plants per 667 square meters, and the row spacing is 2m×3m；; Hedgehog racks can be planted with about 300 plants per 667 square meters, and the row spacing is1m× 2 m. It can be planted in February-March of the following year in the south and March-April in the north.
3. Male plants and female plants are matched. Black tiger is a dioecious plant. When cultivated, the ratio of female plants to male plants should be 9: 1, which is beneficial to cross pollination, and artificial pollination can also be carried out at flowering stage to improve yield.
4. Cultivation methods. There are many fibrous roots in Black tiger, most of which are distributed in shallow soil. Therefore, when planting in mountains and hills, it is not necessary to dig too deep, and it is appropriate to have a length of 0.6 meters and a width of 0.5 meters. Plain, vegetable garden and paddy field don't need to be ditched, so ridge farming is better.
5. Fertilizer and water management. Apply 2000 kilograms of farm manure every 667 square meters, with calcium, magnesium and phosphorus 100 kilograms as base fertilizer; When topdressing, it is necessary to apply thin fertilizer frequently, and it is best to apply fermented cake fertilizer and farmyard manure; Non-bearing seedlings are fertilized 1 time per month, mainly nitrogen fertilizer; Fertilize 1 time about 10 day after seed setting, mainly phosphorus and potassium fertilizer.
6. Pruning techniques. Pruning is generally carried out before flowering in winter 1 month. On the one hand, pruning redundant branches; On the other hand, cut off the winter buds. Generally, trellis cultivation does not need pruning, but both hedge cultivation and pot cultivation should be pruned to control plant type and ensure yield (the main branch of Hei Hu is vegetative branch, which is a vine that controls plant type; Lateral branches are fruiting branches, which control the fruit.
7. Prevention and control of pests and diseases. Strong disease resistance, mainly termites harm roots, inchworm harm leaves and buds.
① To control termites, lime, plant ash or carbofuran can be sprinkled in the planting hole before planting.
② 20% pyrethroid 2000-3000 times solution can be sprayed on the crown to control inchworm.
