Seven points for fruit quality cultivation
I have fruit mulberry germplasm screening and quality cultivation technology since 1997, has worked out a yield of mulberry cultivation techniques and efficient supporting more than 1000 kilograms of mulberry, are presented as follows: First, the choice of suitable raw seed Fruit mulberry fruit is different, mainly divided into two kinds of white and purple. Generally purple varieties have high yields and large fruit types, but their quality is worse than that of white varieties. After selection, the purple varieties that should be selected in the hilly areas of our province include Shannong 321, Dashi, Zhangzhuang No.4, and Limein No.1. The white varieties include Dabaikan, Luzizi and Dongguang Xiaobai. Second, cutting seedling employed Softwood Cutting and hardwood cuttings. The drainage and irrigation conditions were good. The ridges with loose soil were ridiculed. The ridge width was 1.5 meters, the height was 15-20 centimeters, the width of the trench was 50 centimeters, and after the ridges were leveled, the black mulch with a width of 1 meter was covered. The hardwood cuttings were carried out in early March and the greenwood cuttings were carried out from late June to mid-July. Each shoot retains 3 buds, and the spacing of the cuttings is 20 cm x 10 cm. It is advisable to expose l buds on the ridge surface. The branches of the green branches were covered with shade nets, and the shade nets were removed after 1 month. The seedlings propagated in both methods can be planted in the fall of the year. Third, the application of base fertilizer, reasonable honey planted in early March in the first year of planting. Planting trenches 60 cm wide and 50 cm deep before colonization. Each mu of high-quality medlar fertilizer 3000 kg, straw 2000 kg, 45% 50 yuan compound fertilizer. Per plant spacing of 2.4 m X1 m colonization, planting 278 per acre. Fourth, timely fertilizer in early April before and after the full flowering period, foliar spray 0.2% urea and potassium dihydrogen phosphate solution 1 - 2 times; in early July after the end of truncation. Applying 15 kg of urea per acre; In late November, 1500 kg of organic fertilizer is chased after each acre. In case of continuous dry weather, it is necessary to carry out irrigation and drought relief. After the rain, it is necessary to clear the gully immediately. Before and after flowering and during fruit expansion, attention should be paid to timely irrigation and drainage. Fifth, shaping and sparse fruiting fruiting mulberry should adopt "a" shape pruning, when setting a fixed height of about 15 centimeters, when the year along the line to train two trunk, all the remaining buds erased, and in the fall will be 2 main Press into a horizontal shape, showing a "one" shape. In the second year of shoot growth, leave a branch every 15-20 centimeters on the 2 main stems as the third-year result of the mother branch, and all other buds are erased. Bamboo shoots are used to attract new shoots, making them vertical. After the third year of mulberry picking is over, the resulting mother branch is cut from the third bud of the base, and a new resultant mother branch is cultivated in the three buds to prepare for the next year. This is repeated every year afterwards for pruning. Fruit mulberry has a strong ability to produce 9-11 fruits on each result branch. Sparse fruit should be carried out at the flowering stage in early April each year. Each fruiting branch will retain 5-6 fruit and the rest will be removed. 6. Prevention of Pest and Disease Damage The main diseases of fruit mulberry are blight and bud blight. It can be sprayed with stem sulfur in winter every year. In the middle and late April every year, 72% of agricultural streptomycin sulfate and 58% metalaxyl-manganese zinc are sprayed for prevention and treatment. The major pests that cause damage to fruit mulberry are mulberry, etc., and can be painted white on the lignified and semi-lignified parts of the fruit mulberry from mid-June to mid-July each year, or sprayed by enemy killing, artificial capture, etc. Measures to prevent and control. VII. Picking fruit at a proper time When the fruit of the mulberry purple species fades, and the white species grows from greenish to milky white and bright, it can be harvested individually in the early morning. When harvesting, take care not to break the cuticle and collect it in time after harvest.
