Artificial cultivation techniques and management of soft jujube kiwifruit in mountainous area

Cutting seedlings: cutting seedlings in early June. Preparation for cultivation: mainly using hedgerow and scaffolding, it is appropriate to select slightly acidic soil with high humus content and apply sufficient bottom fertilizer. Pruning and shaping: pruning should be carried out in summer and autumn, three main vines should be cultivated in the first 2 years, and then the fruiting branches should be cultivated in the third year. Watering and fertilization: appropriate watering according to growth and climate conditions, topdressing fertilizer twice in the year of cultivation.

I. Cuttage seedling

The main results are as follows: 1. Soft jujube kiwifruit tender wood cuttings in early June, we can choose well-developed new shoots, cut to the part of intact tissue as cuttings, each branch length is about 15cm, retain about 3 buds, remove half of the leaves under the cuttings, and then cover the seedlings with plastic film in the greenhouse.

2. Seedlings can also be raised in the field, the twigs can be planted in the seedbed of fine sandy soil, the cutting depth is 5-6cm, the row spacing of each plant is 5cm, keep the soil moist during the period, shade 5 days before cutting in the field, generally, it can survive and take root after 30 days.

Second, prepare for cultivation

The main results are as follows: 1. the cultivation methods are mainly hedgerow and scaffolding, and the general hedgerow cultivation is more convenient for management. Actinidia chinensis is cultivated in semi-sunny mountain areas with many stones, loose soil, good drainage, high humus content and slightly acidic or neutral soil. but clay plots can not be selected.

2. Before cultivation, the soil preparation needs to be carried out, the depth is 25-30cm, the bottom fertilizer is applied, and then the plant is cultivated to the south of the east-west hedge, with a row spacing of 2.5 × 1.5 meters.

3. After the soft jujube kiwifruit takes root, it is necessary to dig the cave of wide 30cm and deep 35cm, put the seedling into the cave, stretch the root system of soft jujube kiwifruit, fill it with half of the height of the seedling, gently stand firm with your feet, water twice to make the soil moist and then cover the soil.

4. Kiwifruit are mostly female and androgynous plants, so we should pay attention to the allocation of pollination trees when culturing. The proportion of female and male plants is 8:1, which can be cultivated in spring and autumn.

3. Pruning and plastic surgery

The main results are as follows: 1. The branches and leaves of soft jujube kiwifruit grow vigorously, pruning and shaping can improve its yield and life, as well as good cold resistance.

2. Generally, hedges and scaffolding are mainly used for shaping, and pruning is suitable for summer and autumn. Three main vines should be cultivated 2 years before cultivation, and then the fruiting branches should be cultivated in the third year. Proper pruning can make the fruiting mother branches on the lateral vines, and the fruiting branches are more evenly distributed, and the branches can be covered with shelves after 3-4 years of growth.

IV. Watering and fertilization

The main results are as follows: 1. Soft jujube kiwifruit loves a warm and humid environment, and if it encounters drought, it will cause plant death, so the soil can neither be dry nor have too much stagnant water. during this period, it can be watered with fertilization and anti-freezing water before entering winter. water again in spring to promote the growth and development of soft jujube kiwifruit.

2. A small amount of shallow fertilizer should be applied many times. In spring and autumn, base fertilizer can be applied in ditch, and fertilizer should be applied twice in one year. When young trees germinate and begin to grow in the first year of cultivation, the first topdressing should be carried out. Urea, the available nitrogen fertilizer can be selected for topdressing. The second fertilizer can be applied in late July, mixed application of phosphorus and potassium fertilizer, diammonium and 40% potassium sulfate at 2:1. During this period, human feces and urine can also be applied to promote the growth of branches. So as to increase the yield of soft jujube kiwifruit.
