A, planting points

According to the row spacing of 5m digging planting ditch, width, depth of 100 cm × 80 cm. fill the ditch when the topsoil mixed into the organic fertilizer filled into the bottom. Select dry diameter of 1 cm or more, the root system is intact, no pests and diseases, no damage to the robust live seedlings for planting. mid-March dug planting pit, using rectangular planting method, according to conventional planting techniques planted in a timely manner, watering 1 thorough water, and sprayed with the new high-fat film 800 times the liquid can effectively prevent the ground water does not evaporate, the seedling body water does not transpire, isolate pests and shorten the period of slowing down the seedling, so that the plant quickly adapted to the new environment, the healthy growth of the plant. The plant quickly adapts to the new environment and grows healthily.

Second, soil, fertilizer and water management

After the establishment of the garden, in the fall of each year before the freeze on the soil outside the planting ditch to take the expansion of the ditch to change the soil, expanding the ditch 100 cm each year, and will be mixed with the surface layer of organic fertilizer to fill the bottom of the ditch, for the root system to grow to create a good soil environment.

Annually combined with the autumn ditching every 100 cm ditch into 50 kg of organic pigpen fertilizer and 2 kg of nitrate-phosphate compound fertilizer. At the same time each black jujube tree disk 20 kg pig manure fertilizer.

Spring sprouting before irrigation after loosening the soil 1 time, followed by a spray of herbicide, remove weeds in the garden, the whole year **** spray 2 to 3 times, after the autumn fruit harvest, combined with the autumn application of organic fertilizers for the whole garden deep turning.

Three, plastic pruning

1. young tree pruning: thinning out the competition, upright strong branches and dense crowded branches, retraction has been the result of the weak and sagging branches, the center stem extension branch and all levels of the main branch extension branch to be long put.

2. Fruiting tree pruning: medium-density cultivation of black jujube tree in the fifth year into the fruiting season, the pruning task is: thinning peripheral and upper too dense large branches and large branches, improve the inner light, promote the inner hidden bud sprouting new branches; thinning of weak sagging branches, retracting the long fruiting branches, to maintain the momentum of the tree, stabilize the yield.

The wounds caused by pruning are closed in time with a "healing antiseptic film" to prevent dry cracks and the invasion of pests.

Four, disinfection and sterilization

Winter and early spring before budding with the "Tree Protection General" + stone sulfur spray tree, heat preservation and anti-freezing, to eliminate the overwintering of pests and diseases place.

In short, black jujube has early results, easy to manage, resistant to pests and diseases and other excellent characteristics, loved by fruit growers, especially to strengthen the management of the above aspects, to realize the black jujube yield, stable yield.
