Spring Cucumber planting focuses on Management
Cucumber is one of people's favorite vegetables, it contains a variety of sugar, free amino acids, vitamins, cucurbitacin and calcium, phosphorus, iron and so on. Cucurbitacin has antitumor effect. Cucumber also has the effects of clearing heat, diuresis, detoxification, sore throat, hot abdominal pain, etc. Cucumber is generally 3500 plants per mu, 5000-8000 kg per mu, and the income per mu is about 3000 yuan. Cucumber cultivation process is mainly "seed selection-seedling-soil preparation-fertilizer-planting-trestle and vine introduction-fertilizer and water management-pest control" and other links. 1. Variety selection. Jinchun 4 and 5, Jinyou 4 and 6, Jinlu 4 and 6, Zhongnong 6 and 8, Xiangyuan 3 and 1, Xiangchun 3 and 4 should be selected for seedling cultivation in spring. Spring facilities should be selected to facilitate cultivation. Zhongnong 9, 12, 7, Jinchun 1, 2, Jinza 2, 4, Xiangyuan 3, 1, Xiangchun 3, Chunyuan 4, etc. 2. Sowing seedlings. Open field cultivation in mid-March to late April sowing, electric or cold bed seedlings. Facilitated cultivation: Sowing from mid-January to mid-February, seedling raising by electric heating. The amount of seed used per mu is 150 g. Soak seeds in warm water for 15 minutes before sowing, wash and dry, germinate or seed direct seeding. Maintain the soil temperature of about 28℃, 4~5 days can emerge. It is recommended to use a nutrient bowl for seedling raising; after the cotyledons of the seedling bed are unfolded, transplant them on the seedling bed according to the row spacing of 10×10 cm. The seedbed temperature is 18~28℃ in the daytime and not lower than 12℃ at night. When the seedling has one leaf and one core, it is suitable to apply 10% concentration of dejecta removal water once; when the seedling has two leaves and one core, spray 0.1~0.2% potassium dihydrogen phosphate solution once, and apply 20% concentration of dejecta removal water once. 6 - 7 days before transplanting, pay attention to seedling training. 3. Soil dressing. Melon land is not continuous cropping, and loam plots with convenient transportation and good drainage and irrigation conditions are selected. When ploughing, lime is applied 100 kg per mu, and when soil is whole, human manure is applied 2000~3000 kg per mu, and compound fertilizer is 60 kg. Spraying 600 times of Dixon solution on the surface of the bed reduces the occurrence of disease. Ridge surface can be covered with film warming. 4. Colonization. Ground cover and open field cultivation were transplanted from early April to late April, and protected cultivation was transplanted before mid-March. About 3500 plants per mu, after planting, irrigate well the pressure water. 5. Cultivation management. (1) Facility adjustment. March temperature is extremely unstable, occasionally hail occurs, facilities adjustment pay attention to heat preservation and seedling protection, control moisture, in order to prevent disease and freeze. April temperature rises rapidly, occasionally cold air cooling, hail occurs, pay attention to prevention. Facilities cultivation of the master sunny day early open, late close, seedling health. When the local temperature is stable above 10℃, the shed can be removed and the film removed. (2) Build a frame and lead the vine. When the vine is 0.3 meters long, start to insert, erect piles and tie the vine. After erecting the frame, tie the vine in time, tie the vine once every 2~3 days, carry out in the afternoon on sunny days, and let it climb on the horizontal bar. In order to improve the early fruit setting rate of cucumber, 1:50 times of cucumber Baoguo Ling can be sprayed on the pistil or fruit stalk at early stage. (3) Fertilizer water management. Spring cucumber plant growth and development fast, fruit more, need uniform and continuous supply of fertilizer and water. During vegetative growth period, the seedlings were fertilized with 20% concentration of manure water for 3 times. Harvest period, every harvest twice, chase a 30% concentration of strong fruit fertilizer. 0.2% potassium dihydrogen phosphate was applied as foliar topdressing for 1~2 times to delay senescence of functional leaves. (4) Prevention and control of diseases and insect pests. Before five-leaf stage, 80% trichlorfon 1000-fold solution was used to control the damage of yellow cucumber; after planting, 600-fold solution of watermelon continuous cropping agent was used to prevent soil-borne diseases such as fusarium wilt; 40% Yishuangling WP 400-fold solution was used to spray leaves 3~4 times at flowering stage, which could effectively inhibit the damage of downy mildew. 5) Harvest. Cultivation under protected conditions usually begins to harvest from late April to early May; ground cover and open field cultivation begin to harvest in early and mid May. The harvest interval was once every 2~3 days in the early stage and once every 1~2 days in the middle and late stage.

How to plant spring cucumber and chili in greenhouse?
What standard should be reached for the healthy seedlings of spring cucumber in greenhouse? When is it appropriate to plant? For the production of spring cucumber in greenhouse, in order to improve the economic benefit, it is required to harvest as early as possible, and the soil temperature must pass more than 10 ℃ stably. Therefore, only planting larger seedlings can achieve the goal of early maturity. Plant smaller seedlings in the greenhouse.

Key points of Management Technology of Spring Cucumber
First, careful soil preparation, the water content of cucumber seedlings with separate application of organic fertilizer is larger, brittle and easy to break, both afraid of flooding and not resistant to drought, so it is necessary to make the ground level and tilt slightly to one side during soil preparation, so as to facilitate drainage and irrigation, the soil is not bumpy and rich in organic matter. When ploughing and raking the land, it is necessary to apply rotten chicken manure and cake fertilizer in layers.
