What foliar fertilizer can be used for leafy vegetables to make the stems strong and the foliar fertilizer big? There are many kinds of leafy vegetables, many of which belong to leafy vegetables. The leafy vegetables have thick stems and large foliar fertilizer, which can enhance the disease resistance and improve their marketability. What foliar fertilizer can be sprayed to enhance foliar fertilizer of leafy vegetables?

1, spraying nitrogen, phosphorus and potassium fertilizer.

Nitrogen fertilizer can promote the growth of leafy vegetables. Without phosphorus, leafy vegetables will become thinner and smaller. Potassium deficiency will affect the photosynthesis of leafy vegetables. These three nutrients can promote the absorption of each other. When in use, the concentration of urea is controlled at 0.3-0.5%, the concentration of phosphate fertilizer such as calcium superphosphate is controlled at about 0.8%, and the concentration of potash fertilizer such as potassium dihydrogen phosphate is controlled at 0.05-0.1%.

2. Spraying zinc fertilizer

Zinc deficiency in leafy vegetables can easily lead to lobular disease. Therefore, zinc trace element fertilizers such as zinc sulfate heptahydrate should be sprayed and controlled at 0. 1 ~ 0.2%.

3. Seedling-strengthening agent

Seedling-strengthening agent will affect the division of plant cells, make the stem stronger, increase the area and thickness of leaves, greatly enhance the photosynthesis of leaves, and make the leaves dark green. The best application period of seedling strengthening agent is seedling stage, and it is directly sprayed with 1200 times solution evenly.

4. Rapeseed

Rapeseed is a strong foliar fertilizer. Its biggest feature is to promote the growth of roots and seedlings, promote the growth of roots, promote the absorption and utilization of nutrients and water, promote growth and control plant growth. After foliar spraying brassinolide, the chlorophyll content increased significantly, which could improve the commercialization of vegetables. Leaf vegetables can be sprayed with oil throughout the growth period. When sprayed, 5ml of brassinolide can be mixed with 25kg of water.

5. ketamine

Ketamine can inhibit the vertical growth of plants, promote the horizontal growth of plants, make the stems of leafy vegetables stronger, increase the chlorophyll content of leaves and make them thicker. When spraying, spray 1 g with 30 kg of water.

6. Butyl hydrazide

Butyl hydrazide can inhibit the excessive growth of new branches, shorten internodes, increase leaf thickness and chlorophyll content. Leaf vegetables can be sprayed with 85% hydrazide wettable powder 500 times to regulate plant growth.

7. Chloroquine

Withered green grass can stop plants from flourishing, make plants shorter and thicker, and make leaves denser and greener. Spraying water with the concentration of 20-30kg/g.

8. Mepinine

Chlorpyrifos can inhibit the overgrowth of vegetable crops and promote the thickening of leaves. When in use, 20 kilograms of water is sprayed per gram.
