Umper technology for greenhouse vegetable application
Opal is a kind of organic humic acid broad-spectrum active liquid fertilizer. It is a new type of pollution-free multi-component fertilizer produced by the technology of OMS Corporation, the general agent of China National Green Food Corporation and produced by Beijing Opal Biochemical Co., Ltd. and promoted throughout the country. . Ingredients: organic nutrients such as humic acid, humic gums, humates and more than 16 kinds of amino acids, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, manganese, boron, molybdenum and other trace and trace elements . Main effects: Invigorate soil vitality, regulate soil circulation, improve soil structure, and increase the use of soil organic matter and mineral nutrients. After the application of Opal liquid fertilizer, it can promote the growth and development of crops, enhance photosynthesis, improve resistance, improve quality, achieve the purpose of early maturity, high yield and high quality. In 1996, we applied the Opports test in vegetable greenhouses. The results showed that under the same cultivation conditions, the production increase effect after the application of Opportum was obvious, the average yield per mu increased by 18% to 25%, and the output value per mu increased by 450 to 780 yuan. And mention the morning city 7 days to 10 days. The technical highlights are summarized below. First, fruit and vegetable vegetables using root fertilizer technology greenhouse cucumber in the beginning of fruiting cucumbers began to topdressing. During this period, because the plants are still very small, mainly vegetative growth, and the base fertilizer is more abundant, for the purpose of balancing the nutrients, a small amount of Opleor can be applied. The amount of 80 ml of raw liquid per acre is 80 kg of water. When root melons are harvested, as the plants grow, the amount of melons increases, gradually increasing the application amount. Generally, the amount per mu is 100 ml to 250 ml, and the fertilizer is collected every 7 days to 10 days. The total fertilizer is 5 times to 6 times. . Greenhouse tomato is irrigated during the fruit enlargement period. 80 ml of the original liquid per acre is added to 80 kg of water. After each harvest, the fertilizer is chased once and the application amount is gradually increased. The dosage per acre is 100 ml to 200 ml, and the top dressing is usually 4 times-5 times. Times. In the early stage of the results, the green peppers in the greenhouse began to chase the roots in the early stage of scab. The amount of 70 ml of liquid used per acre was 80 kg of water. Every 10 days after the chase once, the amount of 80 ml per acre to 120 ml, a total of 3 to 4 times. Second, leafy vegetables using foliar spray technology cabbage, rape after planting seedlings (5 to 8 true leaves), celery plant height 25 cm to 30 cm began to spray the foliage, the amount of 60 ml per acre to 70 ml 60 kg of water was added and sprayed once every 7 days to 10 days for a total of 2 to 3 sprayings. Third, pay attention to the problem Although the Olpor is a fully-fledged active liquid fertilizer, it is still an auxiliary fertilizer. Applying Opulum liquid fertilizer can stimulate soil vigor, increase the utilization of soil organic matter and mineral nutrients, and provide trace elements needed for crop growth and development. However, the rational application of organic fertilizers and chemical fertilizers is necessary to increase production. In addition, other cultivation measures, such as fieldwork, nursery colonization, weeding, weeding, pest control, and other field operations are managed in the same way.
