High-yield fertilization techniques for several greenhouse vegetables

Cucumber fertilization technology. Before planting cucumbers, you should use high quality organic fertilizer Mushi 5000-7500 kg and 25-30 kg of phosphate 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 a concentration of 0.3% and fertilizers or pesticides Penshibao, growth hormone by mixing melon spirit FengGuo like, to carry out 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 when the size of the dressing should be phased in time, then a large amount of fertilizer needed, should be appropriate to increase the amount of fertilizer. 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 . The amount of fertilizer needed for the second layer of fruit, three layers of fruit, four layers of fruit, and Gypsophila increased gradually, and the amount of fertilizer should be increased in an appropriate amount to meet the nutrients required for the peak period. 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. Winter spinach is sown at the end of the first year of the year, harvested in the spring of the next year, and long periods of dormancy are required in winter. 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 dry winter closure cause 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 fertilizer applicator are taken to avoid the spread of fertilizer in the heart leaves, so as to avoid burn seedlings, fertilizer should be combined with each watering. It can also be sprayed with 0.3% fertilizer concentration and foliar treasure. Spring and autumn spinach spinach and winter spinach basic fertilization techniques are the same.
