1, seedbed requirements: Japanese Hongfeng likes neutral and slightly acidic loose and moist soil. 165438+1in the middle of October, apply organic farmyard manure (pig, sheep and other livestock manure) in the field, with a dosage of 3 tons per mu, evenly apply 50 kilograms of calcium superphosphate and ammonium bicarbonate, turn over more than 30 cm, turn into the bottom of the soil, and naturally decompose and ferment for more than 3 months. There is no need to level the land in winter, and the soil can be loosened by freezing at low temperature to improve the soil looseness and fertility. At the beginning of February, ditching was carried out for border farming. The width of the north-south boundary is1.20cm, the width of the ditch is 40cm, and the depth of the ditch is 20cm, so as to facilitate drainage, field weeding, watering and fertilization.
2. Transplanting: It is best to plant in the middle and lower reaches of the Yangtze River before the new buds germinate in late February. The seedling planting density is 60×60 cm, with two rows per border, and about 1 1,000 plants can be planted per mu. 2-3-year-old seedlings are planted in a single row in each border, and the spacing between plants is 100 cm. After planting, water should be poured once, and then water should be replenished according to the weather and dry and wet conditions.
3. Key points of maintenance: (1) After transplanting the budded seedlings, when the bud joint is red and germinates in early April, the rootstock should be cut off at the top 0.5 cm away from the bud joint, which can be windproof at the seedling stage and can be tied with small sticks. (2) to prevent the harm of ground tigers, longicorn beetles and leaf-eating pests, and check them regularly. (3) Fertilize regularly. Topdressing compound fertilizer in mid-May, early September and early October of 10, and then applying fermented organic fertilizer after defoliation.
