What is the prospect of planting Cornus officinalis in 2020? What are the high-yield planting techniques?

Cornus officinalis, commonly known as jujube, has been planted all over China, the fruit can be used for medicine, edible, tree shape for ornamental, high economic value. What are the prospects for planting Cornus officinalis in 2020? What are the high-yield planting techniques?

I. what is the prospect of planting Cornus officinalis in 2020

Cornus officinalis can treat neurasthenia, vertigo, tinnitus and other symptoms. it is the main medicine of Dihuang pills and Shiquandabu pills. The development of green health food with Cornus officinalis as raw material can be processed into beverages, jams, candied fruits and canned foods. it has high economic value. The market price of Cornus officinalis is 35 yuan / kg, high-quality fruit can reach 46 yuan / kg, the price has risen continuously in recent years, the price is 48 yuan / kg in March 2020, the prospect is promising.

2. High-yield cultivation techniques of Cornus officinalis

1. Select the place

The breeding ground of Cornus officinalis should choose gentle slope or flat land with leeward facing sun, good light, deep soil layer. The soil should be loose, fertile, moist, well-drained sandy loam, near water source and convenient for irrigation, and the soil pH should be neutral or slightly acidic. A leeward sunny hillside at an altitude of 200-1200m with a slope of no more than 20 °- 30 °. It is not suitable to cultivate Cornus officinalis in high mountains, shady slopes, lack of light, heavy soil viscosity, poor drainage and so on.

2. Land preparation

After the seedling site is selected, a deep dig should be carried out before winter, and the suitable depth is 30-40cm. Before sowing, 2500-3000kg of soil fertilizer and 50kg of fully fermented cake fertilizer can be applied per mu. The width of the border is 1.2m, the width of the furrow is 30cm, the height of 25cm is high, and the surface of the border is in the shape of tile back. For the seedling plots prone to mole cricket, grubs and other underground pests, phoxim powder 1.5kg can be sprinkled per mu during soil preparation to control underground pests, and 50% carbendazim 0.5kg is used to disinfect the soil to control nursery blight.

3. Seedling stage management

When the seedlings of Cornus officinalis grow 2 true leaves, the seedling spacing should be 7 cm, weeds should be removed, the seedlings should be ploughed in the first ten days of June, watered once before winter, and the roots of the seedlings should be cultivated to survive the winter safely.

As the seed coat of Cornus officinalis is hard and not easy to germinate, no matter it is sowing in spring or autumn, it should be covered with plastic film in time to keep warm and wet. Under normal circumstances, all the seedlings can come out in one year. After completing the seedlings, we should strengthen the management, loosen the soil and weed at the right time, water according to the soil moisture, and fertilize to promote the growth of the seedlings. When the seedlings are 80-100 cm high, they can be planted out of the nursery.

4. Field management

After planting, weeding was carried out 4-5 times a year, and calcium superphosphate was applied in May and June to promote flower bud differentiation, increase fruit setting rate, and increase wax fertilizer in winter, which could also balance the annual difference of fruit size. Cultivate the soil once in summer to prevent lodging. When the height of the young tree is about 40-60 cm, the top tip is removed in February, 3-4 main branches are selected, and 3-4 secondary main branches are left on the main branch to form a natural happy shape. Young trees are mainly shaped, supplemented by pruning. And because the long and medium-short fruit branches of Cornus officinalis are dominated by apical flower buds, all kinds of fruit branches should not be truncated. Adult trees are pruned in spring and autumn to adjust the contradiction between growth and fruit, renew fruiting branches, retain growing branches, cut short, and promote branches.

The planting prospect of Cornus officinalis is promising, but it also needs to investigate the local market and acquisition, so that it can be foolproof.
