Key points of efficient cultivation of cucumber interplanting kidney bean

Core tip: in mid-January, sow kidney beans 15 cm away from the cucumber row, or raise seedlings in a nutrition bowl and transplant them. The row spacing of kidney bean is 55 cm and the plant spacing is 50 cm. Kidney bean selected Wujin No.1, 851-923 and other excellent disease-resistant varieties, single plant colonization. Interplanting kidney bean with cucumber in solar greenhouse is a cultivation method with high yield and high efficiency. in Northeast China, the output value per mu can reach 12000-13000 yuan, which is welcomed by vegetable farmers. The main points of its cultivation are briefly introduced as follows. 1. Cultivation and management of cucumber 1. The bed soil is prepared to prepare 15 kilograms of high-quality farm manure per square meter in July. After it is fully mature, it will be laid in the greenhouse in the middle of September for hanging ploughing or raking, so that the organic fertilizer can be evenly mixed in the soil. Before planting, diammonium phosphate 60 g / m2 and potassium sulfate 30 g / m2 were used as base fertilizer. two。 Excellent varieties of cucumber such as Jinzao 3, Luning 1 and Xin A were selected. Yunnan black seed pumpkin is used as rootstock. 3. The cultivation of grafted seedlings first raised cucumber seedlings in early October, and then sowed black-seeded pumpkins when the cotyledons of cucumber seedlings flattened. One week later, when the cotyledons of black-seeded pumpkin seedlings flattened and the real leaves were just exposed, the grafting began. The natural temperature in mid-October is very suitable for wound healing. The seedlings were planted immediately after grafting, with small row spacing of 55 cm, large row spacing of 85 cm and plant spacing of 35 cm. This is beneficial to intercropping with kidney beans. After the grafted seedlings were planted, the grafted seedlings should be shaded and moisturized with a small arch shed. After 4-5 days, the seedlings were ventilated with a small arch shed. After about half a month, the cucumber roots were cut off and the hanger was carried out, then normal management was carried out. 4. In the mid-term management of cucumber, the irrigation times of melon seedlings should be reduced in winter, and the irrigation under plastic film or micro-irrigation should be adopted. 30 g / m2 of nitrogen, phosphorus and potassium compound fertilizer was applied before each irrigation. Pay attention to ventilation and dehumidification after irrigation. In order to prevent the occurrence of diseases, Chlorothalonil or Sukeling can be fumigated at night, which can effectively prevent the occurrence of downy mildew, Botrytis cinerea and other diseases. At the same time, foliar fertilizer can be sprayed appropriately in order to increase yield. Cucumbers were harvested at the end of December and were put on the market in large quantities before the Spring Festival. Second, the management of the symbiotic period of cucumber and kidney bean in mid-January, kidney beans were sown in the cucumber row 15 cm away from the cucumber row, or planted in a nutrition bowl. The row spacing of kidney bean is 55 cm and the plant spacing is 50 cm. Kidney bean selected Wujin No.1, 851-923 and other excellent disease-resistant varieties, single plant colonization. When the third group of kidney bean leaves were formed and pinched, the lateral branches were promoted to germinate and the overgrowth was controlled. When the second group of leaves of lateral branches were formed, they were pinched to promote the third branch, which laid the foundation for high yield. During the symbiotic period, the lower low functional leaves of cucumber were cut off in time to improve the permeability and create favorable conditions for cultivating strong kidney bean seedlings. Cucumber and kidney bean symbiosis for about 2 months, according to cucumber seedling status, cucumber price and kidney bean seedling growth and other factors, flexibly determine the time to pull out cucumber seedlings. Third, kidney bean management after pulling cucumber seedlings, the kidney bean rack hanging rope together to improve the lighting conditions between the shelves. Kidney beans blossom and bear pods in late March and begin to show off at the same time. According to the growth of kidney bean, apply appropriate amount of urea and potassium dihydrogen phosphate alternately, combined with foliar fertilization. Kidney bean entered the peak podding period in mid-April, with dense branches and leaves, and high temperature often appeared in the greenhouse. It is necessary to increase ventilation, regulate appropriate temperature and humidity, and prevent flowers and pods from falling. The main disease of kidney bean in greenhouse is Botrytis cinerea, which can be controlled by carbendazim, and the main pests are leaf miner and whitefly, which are fumigated with Miaojing, Aifuding, Yizuanjing and other pesticides, and the control effect is very good. Kidney beans can be harvested until the end of June.
