High-yield fertilization techniques for several greenhouse vegetables

Cucumber fertilization technology. Cucumber before planting, with organic fertilizers should Mushi 5000-7500 kg, 25-30 kg fertilizer base fertilizer. Cucumber melon into the initial first top dressing should be carried out, mu 10-15 kg of nitrogen fertilizer P and K 15-20 kg, 7-10 days to recover after every 1 fertilizer, and combined with water. The whole cucumber was topdressed 8-10 times during the growth period . You can also press mixing growth hormone concentration of 0.3% fertilizer and pesticide spraying or treasure, melon spiritual growth, abundance of fruits, foliar spraying.

Tomato fertilization technology. Yield calculated as 5000 kg, should be applied prior to planting quality manure 5000 kg, 50 kg phosphorus. The first spike fruit enlargement should be 1st egg yolk dressing to size, mu 18-20 kg of nitrogen fertilizer, phosphate fertilizer 15-16 kg, 16-17 kg potash, 2, 3, 4 spike fruit enlargement to egg yolk In large hours, the fertilizer should be applied in time and in a timely manner. At this time, the amount of fertilizer needed should be large, and the amount of topdressing should be increased appropriately. Each top dressing should be combined with watering. It is also possible to use a 0.3% chemical fertilizer combined with a disease-preventing drug for foliar application, or a mixture of seated fruit and fruit .

The fertilization technique of pepper. Before planting, Mushi-quality manure 5000 kg, 50 kg fertilizer base fertilizer. Pepper root enlargement should begin early 1st fertilizer to promote fruit enlargement. Mu has 15-18 kg of nitrogen fertilizer , 18-20 kg of phosphate fertilizer , and 15-17 kg of potassium fertilizer . A second layer of fruit, fruit three, four fruit, stars successively increased nutrient requirement, each time increasing the amount of fertilizer should be adequate to meet the desired results wang nutrients. Each time the top dressing should be combined with soil and watering. Anti-insect and anti-disease drugs can also be mixed with 0.3% of chemical fertilizer concentration, Fengguo, Chiling, etc. for foliar application.

Celery fertilization technology. Should be applied before planting sufficient quality manure 5000 kg, 40 kg fertilizer, plant growth height of 10 cm should be started first top dressing, nitrogen fertilizer mu 7-10 kg, 10-15 kg potassium. Celery into the strong growth, increased nutrient needs, 7-10 days to recover 1 fertilizer, to recover a total of 3-4 time every 15-20 kg of nitrogen fertilizer, phosphate fertilizer 10-20 kg, 20-25 kg Potassium . Each time the top dressing should be combined with watering. It can also be combined with anti-disease drugs to add 0.3% chemical fertilizer concentration and spray Shibao for foliar application.

Spinach fertilization technology. Spinach is divided into winter spinach, spring spinach and autumn spinach according to different production seasons. In late fall and winter spinach head sowing, harvesting next spring days, the need for a long winter's sleep. Therefore, it is especially necessary to pay attention to the fertilization of winter spinach. 4,000 kg of winter spinach per mu , before planting, the acre needs to apply 5000 kg of high- quality organic fertilizer and 40 kg of phosphate fertilizer . The base fertilizer is sufficient and the seedlings grow robustly, which is the key to safe wintering. Before winter, spinach seedlings about 10 cm high, according to the growth needs, 1 winter topdressing fertilizer, nitrogen fertilizer should Mushi 10-15 kg, 10-15 kg phosphorus. Before winter must pour 1 frozen water to prevent seal dry winter caused seedlings died. After the spring of the next year, the seedlings begin to grow, and the topdressing should be carried out in time. The fertilizer should be applied with 20-25 kg of nitrogen fertilizer , 15-20 kg of phosphorus and potassium fertilizer, and the third fat should be pursued every 10-15 days . Spinach topdressing is to use the application, should not spread the fertilizer in the heart leaves, so as not to cause burning seedlings, each time the top dressing should be combined with watering. It can also be sprayed with 0.3% fertilizer concentration and foliar treasure. The fertilization techniques of spring spinach and autumn spinach are basically the same as winter spinach.
