In general, February is the planting period of greenhouse early-warming and hi-temperature fruit and vegetables. In March, it is the planting period of greenhouses and greenhouses. However, driven by economic benefits, many vegetable farmers are cultivating plants early because they can be planted as early as possible, harvest as early as possible, and receive early harvests. Early planting, in addition to preventing low temperatures, but also pouring the first water after planting seedlings, which has a lot to do with early maturity. For many years, the approach of vegetable growers was to apply the base fertilizer → plowing the soil to open the soil → to open the ditch by row spacing → to set the seedlings according to the spacing of the plants → to seal the ditch → flood irrigation with large floods → to loosen the seedlings after a few days. But there are many drawbacks to this: A large amount of soluble nutrients in the soil are lost in protected land production. In order to win high yields, vegetable farmers use large amounts of base fertilizer. In particular, some vegetable farmers in order to save labor, with hundreds of pounds of quick-acting fertilizers instead of organic fertilizer as a base fertilizer, and a one-time application. If the first water after transplanting is flooded, it will cause some soluble nutrients in the soil to infiltrate into the aquifer with the infiltration of water. This wastes fertilizer and pollutes the groundwater source. Water resources are wasted in a large amount China's water resources are relatively scarce, so water conservation should be a matter of common concern to everyone, especially the potential for saving water in agriculture. For example, in drought-prone Xinjiang, drip irrigation has now spread throughout the agricultural areas. This water-saving irrigation method can save 50% of water on the premise of ensuring normal crop growth. However, at present, most people in the central and western agricultural areas in China have not yet realized the significance of water saving in agriculture. Especially in vegetable production, regardless of the size of the seedlings and the amount of water needed, the vegetable growers are water-free regardless of their thickness and consistency. It's a pity that %~80% of the water is lost as ineffective water. Slow rise of ground temperature is not favorable for hair trees. In low temperature seasons, a large amount of water will lead to more soil moisture, poor ventilation, and difficulty in recovering the ground temperature for a long time. This makes the root system easily exposed to low temperature and high humidity. The "root" phenomenon of dead seedlings. In the early spring, when watering in the low temperature season, the water volume should be small. Second, the well water must be poured. Because the well water temperature is also 13°C~14°C when the temperature is low, the impact on the ground temperature after pouring is small. In addition, the well water is directly introduced into the shed by the pipe so as not to be excessively long, so as to prevent the water temperature from dropping during transportation. The serious soil-borne diseases and the increase of the space humidity are currently serious in the production of protected land due to the heavy ramming, and it is difficult to change soils. Soil-borne diseases are becoming increasingly serious. The flood irrigation provided conditions for the spread of germs in the soil, and also increased the air humidity in the shed, creating conditions for the occurrence and spread of leaf disease. How to overcome these problems in the flooding irrigation of vegetables when planting, the author suggested that: the day before the planting of vegetables, the first watering the seedbed, and then spraying insecticide, fungicides, so that seedlings "carrying water with medicine" colonization. Take a watering place → Applying base fertilizer → Plowing the soil → Open the ditch by row spacing → Place the seedlings by the planting distance → Seal the semi-trenchy soil to stabilize the seedlings → Pour the ditch to pour water or use a bowl Each plant will pour about 0.5 kg of water → Seal ditch → After a few days, the method of planting seedlings by loose soil can not only meet the needs of the growth of seedlings in the early stage of seedlings, but also overcome the disadvantages caused by the flooding irrigation after the traditional seedlings are transplanted.

To change the habit of flooding vegetables after transplanting
Since the beginning of spring, the sunshine hours have increased and the temperature has begun to rise. Taking Zhengzhou City as an example, the average monthly temperature in February reached 2.2°C, 2.5°C higher than the average temperature of January-0.3°C. However, from the point of view of climatology, when the average temperature is less than 10°C (when five days is one waiting time), it is still winter, and cold currents often invade. Therefore, the early spring vegetables must be planted according to their own ability to protect the insulation, not blindly.
