What are the key points of white cucumber cultivation techniques?
White cucumber is a variety of cucumber. It differs from the common cucumber varieties we usually see and is rarely seen in cities, but it is fairly common in rural areas. It also stores well, so many farmers like to grow it. Below, let's take a look at white cucumber cultivation techniques with the editor.
1. Land preparation and fertilization
White cucumber can grow in ordinary soil, but it is best to choose a plot with deep soil, loose and fertile texture, and rich organic matter for planting. Before planting, plow several times and use the sun to kill underground pests. Apply 5000 kg of high-quality farmyard manure, 50 kg of nitrogen-phosphorus-potassium compound fertilizer, and 20-50 kg of superphosphate per mu, spread them evenly on the ground, plow them in deeply, then make beds and wait for sowing.
2. Grow strong seedlings
White cucumber can be sown in spring or autumn. Generally, in southern regions, sowing and seedling raising are usually done in March, or in autumn from June to July. When raising seedlings, sawdust can be used. Sawdust has excellent permeability and heat and moisture retention, so the seedlings can break through the soil as quickly as possible, and the roots are not easily damaged during seedling separation. Strong seedlings are required to have a stem thickness of about 1 cm, 4-5 true leaves, thick and green leaves, and many thick and strong roots.
3. Strengthen fertilizer and water management
During the growth period of white cucumber, promotion and control should be combined so that during plant growth, cultivation and weeding measures are done well in the early growth stage, and seedling hardening is carried out. It is advisable to harden the seedlings until the root cucumber is set steadily, and water only after the vines can hold the cucumbers. This avoids watering too early, which can cause excessive vegetative growth and the possibility of fruit abortion. In the early flowering stage, control should be the main approach, while in the fruiting stage, promotion should be the main approach. The principle of topdressing is frequent application and light application. After harvest, apply 20 kg of ammonium bicarbonate per mu as topdressing to achieve stable and high yield.
4. Pest and disease control
The main diseases of white cucumber include downy mildew, angular leaf spot, and powdery mildew, which can be controlled by spraying streptomycin, thiophanate-methyl, and triadimefon. The main pests include aphids, yellow squash beetles, and black squash beetles, which can be controlled with dimethoate, imidacloprid, and trichlorfon, with good results. In addition, white cucumber is eaten as a tender fruit. When the fruit has grown to a certain length and thickness but the seeds and skin have not yet hardened, it should be harvested in time to avoid affecting the taste and quality.
