In the previous article, we talked about the cultivation techniques of melon vegetables. Today, Hui Nong.com will introduce you to the cultivation techniques of leafy vegetables. Common leafy vegetables include Chinese cabbage, leaf mustard, sauerkraut, leeks, spinach, and leeks. Most leafy vegetables have a large demand for nutrients, because many plants are planted every year, and there are many nutrients taken from the soil, and there are special needs for certain nutrients, such as large demand for potassium and calcium, and sensitive to boron and molybdenum. . If you don't understand these needs, just sprinkle some compound fertilizer, spray high-nitrogen foliar fertilizer and hope that the vegetables you produce can sell high prices, then it is underestimating the cultivation techniques of leafy vegetables. 1. Early stage of seedling stage (3-5 leaves) In addition to the large amount of nitrogen required to produce high-yield and high-quality leafy vegetables, these nutrients are also essential! Phosphorus-phosphorus is an important element in promoting roots and strong seedlings. Phosphorus-deficient plants are short and directly reduce yield; Calcium - Increases leaf thickness and stem firmness, improves disease resistance and reduces rotten leaves. Calcium-deficient leaves are prone to shrinkage and deformity, and dried cabbages are severely burnt; Magnesium and trace elements - promote green leaves, strong photosynthesis, greatly reduced yellow leaves, high proportion of commercial vegetables; Common problems: poor root system, weak seedlings, easy to kill seedlings, low survival rate. 2. Late seedling stage Leafy vegetables grow rapidly and planting density is high. Many people promote the growth by applying high nitrogen fertilizer, but partial application of nitrogen fertilizer leads to long leaves and poor root development, and it is difficult to continue to supply the nutrients needed for leafy vegetables, resulting in easy premature aging, picking period. Short, low yield; weak leaves, weak disease resistance, and more diseases. Most leafy vegetables are shallow roots and are sensitive to soil available nutrients. Once the nutrient supply is insufficient, the growth is slow and the leaves are yellow. Therefore, when fertilizing NPK, it is necessary to add trace elements such as phosphorus, calcium, potassium, zinc and boron. Phosphorus supplementation, promote root development, new leaves germination, rapid growth; calcium supplementation, white roots, strong ability to absorb fertilizer, leaf hypertrophy, reduce disease, increase yield; supplement potassium, improve yield and quality; supplement zinc and boron, prevent yellow leaves, deformity. Frequently Asked Questions: Plants are short, have poor growth, yellow leaves, premature aging, and low yield. The above is the technology of leafy vegetable cultivation organized by Huinong. I have learned it? Leafy vegetables have a wide range of needs in life, and it is not difficult to plant. As long as you plant them patiently, I believe everyone will have a good income!
