Abstract

The invention discloses a water culture nutrient liquid fertilizer for preventing and controlling pumpkin powdery mildew. The water culture nutrient liquid fertilizer is characterized by being prepared from the following raw materials and components in parts by weight: 9 to 12 parts of urtica liquid, 5 to 7 parts of chitosan solution, 2 to 4 parts of mixed agent, 3 to 4 parts of magnesium sulfate, 3 to 5 parts of monopotassium phosphate, 3 to 5 parts of ammonium molybdate, 0.8 to 1.2 parts of trace elements, 0.5 to 0.7 part of compound sodium nitrophenolate, 0.5 to 0.7 part of indolebutyric acid, 3 to 5 parts of boric acid, 2 to 3 parts of polyvinyl alcohol and 0.8 to 1.2 parts of Arabic gum. The water culture nutrient liquid fertilizer has the advantages that the activity of multiple types of enzymes in pumpkin is enhanced, the root development of a pumpkin plant is quickly promoted, and the root rotting of the pumpkin in a growth period is greatly reduced; the growth cycle of the pumpkin is shortened, the cell activity is improved, the metabolism is accelerated, the original quick-killing characteristic of each type of insecticidal is maintained, the releasing time of a pesticide is obviously prolonged, required nutrients in the growth period of the pumpkin are supplemented, the stress resistance abilities of the pumpkin, such as virus and disease resistance and drought resistance, are improved, and the utilization rates of the fertilizer and water are improved.

Description

technical field

[0001] The invention relates to the technical field of plant nutrient solution, in particular to a hydroponic nutrient solution fertilizer for preventing and treating pumpkin powdery mildew. Background technique

[0002] During the vegetative growth period of pumpkins in the field, attention should be paid to maintaining temperature and humidity, timely ventilation and intertillage and weeding. Regular fertilization during the reproductive growth period: topdressing urea for the first time when the vines are stretched and before flowering is combined with ridge sealing. For the second time, when the fruit diameter grows to about 12 cm, the compound fertilizer and organic fertilizer containing more phosphorus and potassium are topdressed. Timely pruning and pressing of vines: pruning mainly adopts single vine pruning, leaving only one main vine for each plant, and removing all side vines. Due to the limitation of ventilation in the greenhouse, artificial ass...
