1. Selection of land for planting and planting should be based on topography of high dryness, well-drained loam or sandy loam, sunny slope (5 to 15 degrees slope) or raw and secondary wasteland. In the fall, it was plowed many times, reaching a depth of about 40 centimeters, and then 3 plows and 3 plows to make the soil weathered. Sichuan and other places are planted in 3-7, and the grass is burned before being turned to the ground in order to increase soil nutrients and eliminate pests and diseases. Simultaneous soil preparation for soil disinfection. Then, the construction of Sanqi Garden, each garden area of ​​2 to 3 acres, made of rectangular, 20 to 30 meters wide, 60-70 meters long, separated by 3 to 4 meters between each garden, favorable air circulation, ease of field management. 2. A shady shed was built on the 37th of July. Artificial cultivation required scaffolding to be shaded. The height of the shed is 1.5-1.8 meters, the length of the pile is 2-2.3 meters, and the soil is 50 centimeters. Each row consists of 1 row in the middle, one pile every 2 meters, and an edge shed around it. On the downwind side, the garden gates are opened and closed to adjust the humidity in the shed. Shed materials are made on the spot. Generally, wood or cement prefabricated bars are used as shed columns. The roof pulls the wire as a beam, and then weaves the bamboo into a square and lays a roof cover. Used to adjust shade or transparency. Then, apply enough basal fertilizer and plough it once more. It is 1.3 meters wide and 30-40 centimeters high. 3. Transplanting can be divided into winter and spring planting. Winter plants are preferred, and winter plants are planted with 1 year seedlings. They are generally transplanted from late November to December and completed before germination of dormant buds. First, carefully dig the seedlings and do not injure the roots. Then, according to the large, medium, and small grading plantings, it is advantageous to produce seedlings that are neat and easy to manage. Before planting, the yellow leaves of the seedlings are cut off, soaked with 1:1:200 Bordeaux mixture for 10-15 minutes, or soaked for 10 minutes with 0.3 degree lime sulfur, and then taken out for drying and planted. When planting, in the entire good planting site, according to the large, medium and small seedlings, respectively, according to the line spacing: 1717 cm, 1713 cm, 1313 cm open hole, hole depth 3 cm, each hole into a 37 seedlings. The buds will be placed in the cave. On the flat ground, you can also open horizontal trenches on the surface of the medlar, 3 to 5 centimeters deep, 1515 centimeters in line spacing, and put the seedlings evenly into the ditch. After planting, cover the fine soil, 1.5 centimeters thick, and finally cover the grass with the thickness of the soil not to see the degree; then pour 1 time permeable. Article planting, row spacing 15 cm. About 20,000 seedlings per mu need to be planted. China Agricultural Network Editor
