Cucumber fertilization should be reasonable ratio of N, P and K
Recently, Guo Xuezhong, a vegetable farmer on the river bank in Wei County, who went to Inner Mongolia to plant cucumbers in greenhouses, reported that the outbreak of cucumbers in greenhouses he grew up outside was very troublesome. Old Guo's greenhouse cucumber applied 50 kg of urea per hectare and 50 kg of diammonium phosphate. After the cucumber entered the end of the season, 40 kg of urea was topdressed. Now the leaves and edges of cucumber leaves are yellowing, and gradually spread to the interstitial mesophyll. The lower leaves are partially scorched, curled, wilted, and have brown spots, and gradually develop towards the upper leaves, and the fruit development is hindered. According to the judgment of the situation, this is the imbalance of nitrogen, phosphorus and potassium, serious shortage of potassium, excessive nitrogen fertilizer, and even the typical symptoms of calcium deficiency. The absorption of potassium by cucumber during the fruiting period is higher than that of nitrogen, whereas the cucumber in the greenhouse of old Guo has a scarce shortage of potassium, and the nitrogen is excessive. This increases the concentration of soil solution, and reduces and inhibits the absorption of calcium by roots, resulting in Calcium deficiency. To this end, he was advised to use a high-potassium-rich 55% Eurasian brand multi-functional water-soluble fertilizer, 6 kg per mu, and spraying 2-3 times with puffed fruit potassium, Tieneng calcium, calorific boron and rare earth.
