It is crucial for citrus to produce high potassium

Farmers' friends often pay attention to the application of nitrogen fertilizer in agricultural production, but ignore the application of phosphorus, potash fertilizer and other trace elements, thus causing certain negative impact on crop yield and quality. Here are some ways to identify crop fat-defficiency diseases through fruit leaves to guide farmers' friends to better engage in production.

Potassium deficiency: The tip and upper leaf margin of the old citrus leaves turn yellow first, and gradually expand to the lower part and turn into yellow-brown to brown scorch. The leaf margin curls upwards, the leaves are deformed, the tip of the leaf is withered; the top of the crown is weak and weak. The new shoots are slender and the leaves are small; when the potassium is severely deficient, a large number of deciduous shoots are withered at the flowering stage, and the shoots are withered; the skin is thin and smooth, the juice is less sour and perishable; the roots grow poorly, and the whole tree grows declining.

Boron deficiency: firstly at the top, as if the top stopped growing; roots undeveloped; leaves dark green, small leaves, hypertrophy, young leaves deformity, shrinkage; irregular retreat between veins; flower development is not perfect, the ear is not In fact, roots, berry heart rot and necrosis. Such as soybean "bud blight", apple "stubbing", celery "stem cracking disease", radish "heart rot" and so on are the reasons for the lack of boron.

Zinc deficiency: leaves bleed, leaves cluster, spots appear on both sides of the leaves, the plants are short, internode shortening, growth period delayed. If the tree lobular disease, white corn seedlings and so on.

Experts recommend: "High-potassium red" high-efficiency foliar fertilizer is rich in potassium and manganese, boron, zinc and other trace elements, is your preferred diverting nitrogen, potassium supplement micro-pharmacy.
