Now is the key period for the management of cauliflower in early spring. For example, cauliflower, broccoli and broccoli cultivated in early spring have entered the stage of water and fertilizer management. Let's study the key points of water and fertilizer management of cauliflower in the next March with Huinong. First, water Impact on crop growth: 1. Raw materials for photosynthesis. - indirectly affecting production 2. The regulation of water on the living environment of crops. Moisture can increase atmospheric humidity, improve the temperature of the soil and the surface atmosphere of the soil. - directly affect crop growth 3. Water is a regulator of the body temperature of crops. Water molecules have a high heat of vaporization and specific heat capacity, so in the case of fluctuations in ambient temperature, a large amount of water in the plant can maintain relatively stable body temperature. Under the scorching sun, the body temperature is lowered by transpiration to reduce the body temperature, making the plants less susceptible to high temperatures. - directly affect crop growth Second, fat Impact on crop growth: 1. In addition to absorbing water from the soil, crops also absorb mineral elements and nitrogen as well as organic matter to maintain normal life activities. 2. The amount of mineral elements and organic matter in the soil directly affects the growth and development of the crop. Under the cultivation conditions, the type and amount of fertilizer can change the proportion of nutrients in the soil and provide a good nutrient environment for plant growth. Third, cauliflower water and fertilizer management practices It is necessary to attack the water and fertilizer, and apply 15~20kg of quick-acting nitrogen fertilizer per acre with water. It can also spray foliar fertilizer or 0.3% urea solution on the leaf surface to promote vegetative growth and release the tree as soon as possible. Every winter or spring planting cauliflower, broccoli will appear "early flower" phenomenon, mostly due to plant growth in the early stage, vegetable farmers are neglected in water and fertilizer management (water and fertilizer supply is not timely, insufficient), plant vegetative growth is too weak, the tree does not grow up of. Please be sure to pay attention in advance to avoid losses. The above is the main point of water and fertilizer management in cauliflower in March. Please have a need to seriously consider and learn. Welcome everyone to continue to pay attention to Hui Nong Network!
