Planting density and method. Generally, the plant spacing is 2× 1.0m, with 334 piers per mu and each nest 1 seedling. Planting time is mainly in spring, summer, autumn and winter. Planting method: on the whole land, according to the predetermined row spacing, mark the planting points with lime and arrange them in rows. Dig a pit with a length of 30-40cm, a width of 30cm and a depth of 30cm around the planting site, then place the seedlings in the center, fill the soil steadily, water 2.5-3kg, and then seal the pier and cultivate the soil.
Second, pruning and shaping.
Pruning method of planting 1- 2 young pier: mainly plastic, supplemented by flowering. Focus on cultivating primary and secondary backbone branches to form a solid backbone framework, laying the foundation for comprehensive high yield in the future. In the first year, select robust branches from the planned pier shapes. Leave one for the natural round head shape and one for the umbrella shape. Leave 3-5 knots for each branch, cut off the upper part, and cut off all other branches. In the future management, we should always pay attention to removing branches from roots in time to prevent excessive tillering and affect the growth of trunk. In the second year, the main task of pruning during this period is to cultivate first-class backbone branches. After pruning in the first year, under the general conditions of fertilizer and water management, 6- 10 purple branches will grow, 3 -5 natural round-headed branches and 6-7 umbrella-shaped branches will be selected as the first-class backbone branches, and 3-5 sections will be left for each branch to cut off the upper part. No matter where other branches grow, especially the tillers at the base, they are all thinned out.
Third, intertillage weeding
After planting honeysuckle, it is necessary to regularly weed and loosen the soil so that there are no weeds around the plant to facilitate growth. After thawing the ground in spring and before freezing in autumn, intertillage, loosen soil, weed and cultivate soil. The soil should be cultivated once a year before the new buds germinate in early spring and before freezing in late autumn and early winter. This can improve the ground temperature, prevent drought and moisture, promote the development of root system, and make more branches and flowers.
Fourth, fertilization.
When honeysuckle is cultivated, fertilization is generally carried out in early spring or early winter every year. Specifically, when the first crop of flowers is about to be harvested in early spring and before winter, an annular ditch is opened around the plants, and the organic fertilizer and chemical fertilizer are mixed and applied to cover the soil, so as to preserve water and fertilizer. Topdressing should be combined with intertillage weeding. In spring and summer, it is mainly to apply sparse human and animal manure, with an acre1000-2,000 kg. Never use too thick human and animal manure. The amount of fertilizer depends on the size of the flower pier. 5 kg for those over 5 years old; Soil and miscellaneous fertilizers should be applied to each plant in spring; Ammonium sulfate 50-100g; Calcium superphosphate150-200g; Or 5-10 kg of human and animal feces; For children under 5 years old, the dose should be reduced. If the soil is fertile, you can apply less or no fertilizer to prevent plants from growing wildly. After the first flower, topdressing chemical fertilizer is the main method. Using 250g urea, 0/250 g superphosphate/kloc-0 and 50kg water per mu, foliar fertilization, rejuvenation and yield increase are also obvious. Before winter, apply decomposed compost and manure, and add cake fertilizer as appropriate to help winter. In dry weather, water the soil in time to keep it moist. In addition, when flower bud differentiation is seen before each crop, spraying 200-300 mg/L diammonium phosphate on the leaves can promote plant growth and increase the yield of medicinal materials by 20%. It is best to apply fertilizer once after each flower picking, mainly urea chemical fertilizer, to increase the number of flower picking.
Five, land selection and land preparation. Lazy honeysuckle is sunny and tolerant to shade, so it should be planted in sandy loam with abundant sunshine, deep soil layer, fertile and loose soil, good ventilation and drainage, and the slope below 15. The three new varieties grow vigorously, have compact crowns and are easy to form flower buds. They have the characteristics that new branches can develop into flower branches in the same year and can bloom when planted in the same year. They have good high-yield characteristics and are suitable for close planting. The plant spacing should be 2m× 2m or 2m×1.0m. When preparing soil, the method of digging holes can be adopted, and the specification is 70cm× 70cm× 70cm. To apply sufficient base fertilizer, 4000-5000 kg compost, straw or green grass, 150-300 kg calcium magnesium phosphate fertilizer per mu, or 0.2-0.3 kg vegetable cake, 0 0. 15 kg compound fertilizer or/kloc-0.5 kg farm manure per hole.
