In recent years, the Malian jujube industry in Zaoqiang County has developed rapidly and has become a new growth point in the county economy, with broad prospects for development. Malian jujube is not only suitable for the development of Zaoqiang County, but also particularly suitable for the development of similar areas with ecological conditions such as Luanping County, Gucheng County, Wuyi County, Luzhou City, and Xianxian County. Now we will introduce the technical points of Malian jujube winter planting as follows, for reference of fruit growers. 1. Garden choice. Malian jujube is a perennial fruit tree with shallow roots and high light intensity. The result is early, long-lived, drought-tolerant, waterlogging-resistant and salt-tolerant. It can grow in Zaoqiang county and surrounding soil with a pH of 5.8-8.6. The newly-built gardens should be suitable for flats where the terrain is flat, soil is deep (above 80 cm), soil is loose, soil is fertile (more than 1% organic matter content is preferred), light is sufficient, drainage is well maintained, and transportation is convenient and pollution-free. 2. Planting time. The planting time was from early November to early December. After the seedlings were defoliated and before the soil was frozen, the soil moisture was sufficient and the ground temperature was not too low. The roots of the nursery stocks were quickly healed and the survival rate was high. 3. Planting density. Many years of experiments have proved that the Malian jujube should be planted in a single row in a north-south direction, and the row spacing is greater than the plant spacing to facilitate ventilation. Daejeon should choose the planting mode of 3.40 meters and plant 72 jujube trees per acre to ensure the characteristics of jujube trees and make full use of the land. It can also take into account the jujube food, adopting an intercropping system of 4m and 8m, planting 21 jujube trees per acre, intercropping with dwarf crops such as wheat, peanuts and soybeans, and not interplanting high-stem crops such as corn and sorghum. 4. Seedlings pretreatment. Choose seedlings with a height of 1.6 meters, a breast diameter of 2 centimeters or more, pure lines, complete pruning wounds, good healing without pests and diseases, and mechanical damage, so that the seedlings will be planted with transportation, and the overnight seedlings will be soaked with water 16 to 24 Hours can be used. To increase the survival rate, seedlings should be treated with rooting powder before planting. The rooting powder No. 3 should be dissolved with a small amount of alcohol, diluted with fresh water 15,000 to 20000 times, sprayed on the root system (or directly rooted), and the wet grass cover the shade, 2 Planted after childhood. 5. Planting points. According to the plan to pull the line, fixed point, open hole, digging 80 to 100 cm square, deep 60 cm of the planting hole, preparing 15 kg of decomposed farmyard fertilizer and disinfection of chicken manure 2 kg, the fertilizer and the upper layer of the original soil fully mixed, layered backfill, Then raise the seedlings, righting, pragmatism, planting water on the day of the planting, pouring two waters on the 6th day, and then soiling the base soil (30 cm high, leaving a slope of 45 degrees, pay attention to thawing in the spring after 2 or 3 times). Or cover the 60cm radius centered on the dry center with a plastic film to reduce the evaporation of moisture in the soil and keep it warm. 6. Post-plant management. Apply 1 meter or less of main seedlings to brush whitening agent (formula 18 kilograms of water + 2.5 kilograms of salt + 0.1 kilograms of vegetable oil + 0.05 kilograms of starch + 0.75 kilograms of sulfur powder) and add an anticaries agent to prevent insect pests, livestock bites, and water evaporation , sunburn hazards, winter frostbite, and depending on weather conditions and soil moisture, timely irrigation.
