Is potassium dihydrogen phosphate a foliar fertilizer?
Potassium dihydrogen phosphate is considered a high-quality phosphorus and potassium fertilizer that plays a significant role in the later stage of crop growth. Then, what is the appropriate concentration of potassium dihydrogen phosphate when used as foliar fertilizer? When is it better to use it? Let’s find out together below.
Concentration of potassium dihydrogen phosphate foliar fertilizer
Potassium dihydrogen phosphate contains phosphorus and potassium elements, which have a key effect on the growth and development of crops in the later stage. Especially for solanaceous fruits, melons, and vegetables, the application of potassium dihydrogen phosphate can increase production and improve the quality of crops. The concentration of application varies due to different methods:
1. Seed soaking and mixing: If potassium dihydrogen phosphate is used for seed soaking and mixing, the concentration ratio is 1:500, which means 1g of potassium dihydrogen phosphate should be diluted with 500g of water, or 1 jin of water. It has a very good promoting effect on seed germination and root expansion.
2. Foliar spray: If potassium dihydrogen phosphate is used for foliar spray, the concentration should be 1:800 or 1000. This concentration is mostly used on solanaceous fruits, to improve fruit size, taste, and sugar content, that is, 100g of dihydrogen phosphate should be diluted with 80-100Kg of water, and the water requirement for spraying per mu is about 40Kg.
3. Root application: For crops with large fertilization amounts such as luffa and green beans, it is necessary to apply good fertilizer every crop. The proportion of potassium dihydrogen phosphate for root application is 1:1000, and the water requirement per mu is about 100Kg. Each seedling needs to be irrigated with 10-20 grams.
Application time of potassium dihydrogen phosphate
If potassium dihydrogen phosphate is used for foliar spray, the application time should be controlled in the morning and evening. If there is more precipitation and temperature in the local area, and it is not the kind of heavy rain temperature, in order not to delay the fertilization of crops, a certain amount of organosilicon material can be added to the diluted liquid fertilizer, which can improve the adhesion ability of the fertilizer solution on the leaves of green plants and accelerate its penetration and absorption.
Attention: Due to the high quality and excellent effect of potassium dihydrogen phosphate, it is necessary to control the concentration value when applying it to crops, and if not, consult the staff of agricultural production materials.
