All the physiological activities of the teak, the metabolism is inseparable from the role of water. The water is absorbed by the epidermal cells of the root, and the mycorrhiza is absorbed into the xylem duct through the cortex and the endothelium, and then transported upwards into the trunk and the main branch duct by the duct, and then enters the leaf of the shoot and then to the mesophyll cells, which are transcribed into the air by the stomata to form transpiration. Pull the water. Another type of pressure that is caused by root metabolism to increase the flow of water depends on the root pressure to cause water absorption to be actively absorbed.
The grapefruit tree water and fertilizer management has its main points in all seasons. The grapefruit farmers should pay attention to the management of water to dissolve the minerals in the soil, so that it can be absorbed through the root system. If the soil is dehydrated, the root absorption capacity and photosynthesis will be reduced, and the transportation of various mineral nutrients and photosynthesis products in the tree will be hindered. If the orchard is poorly drained or over-irrigated, the soil is deprived of oxygen, forcing the roots to be anaerobic. Breathing, causing rotten roots, thereby affecting tree growth and yield. Mountain orchards should pay attention to water diversion, water storage, establishment of tube irrigation, drip irrigation, and sprinkler irrigation facilities to prevent the pomelo trees from suffering from drought. Especially in the sapling stage, the drought-proof irrigation in the result period, to maintain sufficient water supply to reach fast-growing and high-yield. On the premise of ensuring the water supply of teak trees in the fields, riverside continents and low-lying land, flood control and drainage should be done, and the groundwater level should be lowered to keep the soil in a state of ventilation.
According to the demand for water and climate rainfall during the various growth stages of the pomelo, the following points should be noted in the water management of each season:
Yesterday we first introduced the water and fertilizer management in winter, mainly because it has entered the winter. If I can talk about water and fertilizer management in winter, I will give priority to winter water and fertilizer management. As for other seasons, we will talk about water and fertilizer management in the spring today. There will be water and fertilizer management in summer and autumn. Time is abundant, you can talk about it one by one.
The grapefruit tree water and fertilizer management has its main points in all seasons. The grapefruit farmers should pay attention to management. Then we will talk about spring now.
Moisturizing and moisturizing in spring: Spring is a period of germination, shooting and flowering of pomelo trees. It is necessary to have a proper amount of water to make the grapefruit shoots neat and healthy and flowering normal. At this time, there is more rain, so pay attention to drainage, not only to maintain the moisture of the soil, but also to prevent the accumulation of water in the soil. Watering in the spring should be timely watered to prevent the development of shoots and flowers affected by drought. However, the air humidity in spring is large, and it is not suitable for irrigation or drip irrigation during the tender shoot period, so as not to induce disease. The application of mulching film in the orchard can achieve water retention and moisturization, increase soil moisture, reduce weeds, and increase yield.
