Organic ecological soilless vegetables promotion
Environmentally harmless products Product-friendly organic eco-type soil-less cultured vegetables Promotion organic eco-type Soilless cultivation has the characteristics of investment, low cost, low labor, easy operation, high quality and high efficiency, and is a practical change from traditional to modern in the cultivation of vegetable facilities. new technology. Using this technology to produce pollution-free vegetables, reducing costs and increasing efficiency, the product meets the national pollution-free food hygiene standards. Practice has proved that this model can produce high-quality vegetables on an annual basis without being affected by the external environment such as climate. Construction of cultivation system Shed structure A plastic greenhouse made of steel pipe structure, 30 meters long, 7 meters wide, 3.3 meters high, 1.2 meters high on the shoulder, the film wind, ventilation area of ​​40%, and covered insect nets. The insulation film was selected to cover the shed and the top of the roof was covered with the active shade net. The cultivated substrate was derived from a rich source of Chinese medicine slag and Hesha, with a ratio of 2:1. Each square meter of the matrix is ​​mixed with 5 kg of puffed chicken manure and peanut bran, 1 kg of ternary compound fertilizer and pH 6.5-7.0. Planting tank planting tank length 29 meters, width 1 meter, depth 0.3 meters, 0.35 meters spacing between slots, slope 1:150, the bottom of the shop shop PE film. Fill in the mixed culture substrate. Grooves and surrounding slabs of cement are used for both sidewalks and field cleaning. The draught irrigation system for the installation of the water supply system consists of a main pipe, a branch pipe and a drip hose. Two hoses per groove, hose diameter 25 mm. Preparation of nutrient solution Chicken manure, peanut bran, and compound fertilizer were mixed in a ratio of 1:1:0.2, and then covered with water and stacked for more than 25 days. Remove the film and dry it for use. After soaking the retort organic fertilizer for more than one day with fresh water, the supernatant was diluted to conduct conductivity (EC) of 1.0-2.2 millisieverts/cm and pH 6.5-7.0 for application. Anniversary mode of production Soilless cultivation can produce a variety of vegetables. The annual production takes into account the early, middle and late maturity of different varieties, considering heat resistance, cold resistance, negative resistance, seasonality, etc., placing the vegetables in the most suitable season for growth and development and having the highest value for the commodity. Modes suitable for planting in this region and gaining greater economic benefits are: 1 cabbage from mid-November to mid-November, thick-skinned melons from mid-March to June, tender squash from July to August, and thick-skinned melons From late August to November; 2 (cherry) tomatoes October - March of the following year, cucumbers from April to May, leeks (or leaves with wild vegetables) from June to August, and cucumbers from August to September. The substrate selection technology matrix selection of coconut cocoon and fine sand mix in a 1:1 ratio, mixing 1 kg per square meter of ground chicken manure and peanut bran, compound fertilizer 1 kg, fully mixed into the nursery cup, seedling tray or Nursery bed to be used. Variety selection Choose high-quality and low-light-resistant, high-quality vegetable varieties suitable for facility cultivation or greenhouse special varieties. Such as cherry tomato saints and so on. Soaking germination and seed soaking seeds moisturize after germination. The germinated seeds were seeded in a dripping seedling cup (pan, bed). Leafy vegetables are often broadcast on planting troughs. Seedling management and showering alternately. In general summer watering 2-3 times a day, every day, nutrition solution. Dripping water once in 2-3 days in winter can use one time of water and one application of fertilizer. Age of seedlings is 15-25 days old, and leaf age 2 leaves 1 heart to 3 leaves 1 heart. Planting and Management Prior to planting and colonization, the drip irrigation system's pipes should be well-knotted, with at least one dripper per plant. Substrates penetrating water at one time. The planting density varies according to the season and variety, and should be sparse in spring and summer and autumn and winter should be dense. Nutrition and irrigation Organic fertilizers are mainly based on basal fertilizer supplemented by topdressing. The ratio of base fertilizer and top dressing is 6:4. In the various stages of growth and development in time organic fertilizer applied 3-4 times, usually 20-50 kg / acre, or dubbed EC1.5-2.0 millixi / cm, pH6.5-7.0 nutrient solution alternately with water. Irrigation to keep the matrix wet. No irrigation on cloudy days, and watering every other day in winter to keep the moisture content of matrix at 60%-80%, cover the membrane in the tank, prevent evaporation of moisture, and reduce humidity in the greenhouse. Plant adjustment and harvesting of melon crops grows to 6-8 pieces in true leaves, and when the plants are drawing vines, they are brought up with red string or bamboo. For the main cultivar, remove lateral branches and excessive tendrils, while sparsely fruiting and thinning the fruit, removing malformations early, and picking up the main vine when the main vine grows to a predetermined height, and allowing the collateral fruits to grow downward (cherry) after the tomato plants have bloomed. Thread the base stem with a rope and pull the plant up. Infinite growth type adopts single-dry pruning, and self-sealing type uses double dry pruning to timely remove branches and thinning fruit. The middle fruit type tomato has 4 fruit in the first ear, 5 fruits in the second and third ear, and the cherry tomato can retain fruit. Fresh fruit should be picked when the fruit is bright and bright, sweet and sour. There are two types of melons, one is single and the other is dry and pruning. In the 12th to 15th quarters, there is one fruit of the vine. The main vine leaves 26-28 leaves to pick the heart, and the rest takes the fruit vine. When the melon reticulates prominently, the skin changes color, and the fruit stem appears away from the layer, and the fruit and fruit emits aroma, indicating that the fruit is fully mature and can be harvested.
