Establishment of Kernel Apricot Garden
Apricot trees are fruit trees that like light, drought, waterlogging and frost, so they should choose sunny and dry places to build gardens, not on shady slopes, waterlogged depressions and valleys where cold air is easy to sink.
Apricot is a long-lived fruit tree, generally-200-year-old trees are still rich, and the planned spacing between trees and rows is larger. However, considering the needs of early high yield, temporary plants can be set up at the establishment of the garden, and thinning or transplanting gradually with the increase of tree age. The row spacing of the permanent row can be designed as 4 meters × 6 meters, and the temporary encryption garden is 2 meters × 3 meters. The temporary plants should be dealt with in time when they are about 10 years old. When planning, we should also consider the situation of soil, fertilizer and water. If the soil is fertile, the soil layer is deep, and the water source is sufficient, the plant spacing should be increased by about 1 meter. On the contrary, if the soil is barren and dry, the plant-row spacing can be reduced by about 0.5 meters.
When planting, you should dig a planting ditch of 1 meter deep and 1 meter wide or a planting hole of 1 meter long and 1 meter wide and deep, add barnyard manure to the bottom of the ditch (50 kg of each plant), fill the topsoil and plant the seedlings in the middle, the conventional seedling interface is parallel to the ground, and the original surface of "Sandang" seedlings is parallel to the ground, solid, fully watered, buckle a piece of plastic film to retain water. Dry at 60 cm, cover with a plastic film tube, and remove after spreading the leaves.
Special attention should be paid to pollination trees when planting. In general, the ratio of main varieties to pollinated varieties is 4:1 or 5:1.

Management Technology of Apricot in greenhouse
1. Fertilizer and water management. No fertilizer was applied after plastic film mulching, and 0.3% urea plus 0.2% photosynthetic micro-fertilizer and 0.3% potassium dihydrogen phosphate were sprayed once after fruit-setting and hard-core stage. Drip irrigation pipes are installed in the shed to water reasonably according to the soil moisture. Watering should not be too much, lest the new shoots will flourish and cause physiological fruit drop. two。 Shaping and pruning. "Y"-shaped pruning is mainly lateral branches, proper thinning or utilization of upper dorsal branches, long flat branches, retraction of drooping branches, cutting off dense branches, disease and insect branches and withered branches. 3.

Cultivation techniques of Ziziphus jujuba
The main results are as follows: 1. the selection of garden land Taiwan honey jujube has no strict requirements on soil, acidic soil or soil with slightly higher salinity can grow, but it is suitable to grow on flat land or gentle slope land with pH 5.5-6.5, adequate water supply and good drainage. In the first year of planting in the mountain area, the jujube can be harvested 7.5kg to 10kg, and planted in paddy fields or relatively fertile flat land, each plant can harvest more than 30kg. Second, select the grafted seedlings without disease, insect and mechanical damage. The standard seedlings should be pure in variety, moderate in grafting site and good in healing of graft interface.
