Early Cultivar Cuiguan Pear Cultivation
(1) Planting period and cultivation techniques Cuiguan pear can be planted after falling leaves, and it is best to plant before the Spring Festival, and no later than the end of February. As the saying goes, “The roots are first before the festival, and the first germination is after the festivalâ€. Early species more than late species is conducive to plant growth and development. Before planting, dig holes for planting. The width of the hole is 100 cm and the depth is 80 cm. If the paddy field can be changed to 80 cm wide and 40 to 50 cm deep. In addition, basal fertilizer was applied one month before planting. Each plant had 50 kg of beef fat, 15 kg of chicken manure or 5 kg of vegetable cake. One kilogram of calcium phosphate was added to each hole. When planting, it is necessary to cut a small amount of main roots, cut to the main root until white, cut roots must be flattened, in order to facilitate the growth of new roots. The grafting interface of seedlings must be exposed on the soil surface. Do not grow too deep. At the same time, remove the membrane at the interface of grafting so as not to affect the normal growth of the plant. (2) Planting Density and Arrangement of Pollination Tree In order to put the new orchard into production soon, it is advisable to consider the dense planting at first and then sparse. The plant spacing is 4 meters 2 meters, 83 plants per acre, or 5 meters 2.5 meters, 54 plants per acre. Hillside planting to make terraces, spacing between 2 to 2.5 meters. After production, thinning can be carried out according to tree vigor, seal line status, and results. Pears are fruit trees that are not self-cultivated. Planting Cuiguan Pear requires a variety of flowers with similar flowering time as pollination trees in order to achieve high yields. The proportion of main varieties and pollination varieties should be 2:1 and 4:1. Pollination varieties can choose Huanghua, Qingxiang, crisp green and Xueqing and other varieties.
