Cucumber, alias Cucumber, Courgette, Thorngourd, Hanging Gourd, is a cucurbitaceous plant. The cucumber is male and female with different plants, with shallow roots and weak regenerative ability. It is usually dominated by main vines or vines with dominant vines, and has the capability of parthenocarpy. It is a warm, short-day crop, with a suitable temperature of 21-28°C. It is not tolerant of cold, and growth stops below 10°C. Tolerant to high temperature, the general early-maturing varieties resistant to low temperature, late-maturing varieties are more resistant to high temperatures. First, the selection of varieties According to market requirements, should choose the marketable varieties, combined with the varieties of their own disease resistance, resistance and adaptability, the best choice for spring and autumn and winter plant species. Such as Green Pai Sui You, Sui Nong, Sui-Feng, Spring four, spring five cucumber (crop cultivated in spring and autumn), spike star cucumber (specialized greenhouse type). Second, the selection of sowing 1, select a well-drained, organic-rich, fertile and good water retention and retention of good viscous sandy loam. Former rice dumplings are best for paddy fields and should not be used in conjunction with melon crops. Deep trenches are used, typically 1.8-2.0 meters wide (including trenches). 2. Spring sowing uses germination or seeding, and summer sowing uses live sowing or dry seeding. The specific method of soaking germination is: sterilize with 50-55°C warm water for 10 minutes, keep stirring, then immerse for 4-6 hours with clear water, pick up and drain and place it at a constant temperature of 30°C or in a warm place to germinate. The germination period is washed with water once in the morning and evening. 2-3 days until the germ length 0.5 cm when sowing, after planting in early spring with a plastic film covered with cold. Seedlings use nutrition cups, nutrient plates or nutritious soil blocks, seedling age 15-20 days (0.5-2 true leaves) in sunny evening or cloudy day colonization. Protect the root system when planting, generally 25-35 cm away from the plant, 120-150 grams per acre, 3000-3500 acres per plant, suitable for close planting in summer and autumn. Third, field management 1, fertilization: Shizu base fertilizer is a key measure to stabilize production and high yield, generally Mu Shi fermented organic fertilizer 2000-3000 kg, 60 kg of bran cake, superphosphate 30 kg as base fertilizer. Topdressing is based on the principle of diligence and thin application. The first female flower appears once and fertilizes once after harvesting 1-2 times. Mushi peanut bran 15-20 kg, compound fertilizer 30 kg, and potassium fertilizer 10 kg. In summer and autumn, cucumbers grow rapidly and age quickly. In addition to applying base fertilizers, it is necessary to replenish top dressings, apply fertilizers early, and especially apply phosphorus and potassium fertilizers, so that seedlings can grow vigorously, avoid leggy, and premature aging. 2. Drainage and Irrigation: Following the principle of controlling the water content of cucumber seedlings and flowering results require the most water. 3, soil and scaffolding vines: In the tower before the need for the sorghum and sorghum ditch thoroughly cultivating and weeding, and properly cultivate soil to protect the root system and promote new root growth. Spring cucumbers are usually combined with fertilization to produce soil when the tendrils appear, and then they are inserted into a bamboo frame to introduce vines. In summer and autumn cucumbers, 2-3 pieces of true leaves are usually cultivated once, and after the first harvest, the soil is cultivated for the second time. There are two types of scaffolding: "Rack" and straight-line. Most of them are "Rack". 4. Diseases and Insect Pests Cucumber diseases and pests are relatively large, and diseases, downy mildew, wilt disease, anthracnose, and powdery mildew, which have a greater impact on yield and quality, are mainly pests of the species Huang Shougua, Aphids, and B. utilis. 1. For plague, downy mildew, and anthrax diseases, use can be made of Ledomil, Antivirus, and Thiophanate (import) 800-1000 times. Fusarium wilt can be irrigated with 1000-fold of 70% enemy pine or 4000 times agricultural streptomycin. Powdery mildew can be used triadimefon or thiophanate-methyl 500 times. 2. Drosophila can be controlled by triazophos, and the locust can be killed by 800 times Dimethoate.
