Different vegetables should use different foliar fertilizers

Leaf vegetable top dressing with urea as the main spraying concentration of 0.3% -0.5%, sprayed 75-100 kg per acre, spraying a total of 2-3 times in the whole growth period; can also spray 0.3% rice vinegar solution, per acre Spray about 50 kg.

Foliage top dressing of fruits and vegetables is mainly composed of nitrogen, phosphorus, potassium or multiple compound fertilizers, such as 0.2%-0.3% potassium dihydrogen phosphate solution, 0.5% urea+2% superphosphate and 0.3% potassium sulfate solution, 0.05% rare earth fertilizer solution, etc., generally sprayed 2-3 times during the growth period; spray foliar Bao, photosynthetic fertilizer, etc. applied on fruits and vegetables, but also have a good effect. In addition, when cucumbers are sprayed with 1% glucose or sucrose solution, the sugar content of cucumbers can be significantly increased. The “sugar nitrogen solution” consisting of 0.2% urea+0.2% potassium dihydrogen phosphate+1% sucrose can not only increase Yield, but also enhance the plant's resistance to disease, reduce the incidence of downy mildew and other diseases.

Onion, garlic, root vegetables, and yam vegetables are topdressed with phosphorus and potassium fertilizers, such as 0.2% potassium dihydrogen phosphate solution, superphosphate, and ash leaching. At the same time, according to the lack of trace elements in the soil, spray trace element fertilizer. Such as radish, mustard sprayed 2-3 times 0.1% -0.2% borax solution, can increase production, but also to prevent worry and improve quality. Potatoes spraying 0.1% zinc sulfate + 0.1% ammonium molybdate mixture can generally increase production by about 10%.
