Technical considerations for greenhouse planting What should be paid attention to in Dapeng planting?

1, base fertilizer. It is very important to apply base fertilizer before planting crops. Relatively speaking, the effect of base fertilizer is longer, and sufficient base fertilizer can make crops grow better. Because the weather is very hot in summer, it is not suitable for planting new crops, so the greenhouse will rest for one to three months, which is a good time to apply base fertilizer. Because there is plenty of time, you can use a lot of fertilizer. But if it is winter, because the greenhouse can control the temperature, this crop has been harvested, and the next crop will come almost immediately. Some crops have begun to raise seedlings in advance before even harvesting this crop. Therefore, if basal fertilizer is applied at this time, the time will be shorter and there will be no time to wait for it to ferment. It is safer to use thoroughly treated organic fertilizer.

2. Water resources management. The amount and frequency of watering crops are of course different. For example, in summer and autumn, when the temperature is high, the water evaporates faster, so after transplanting vegetables, the water volume will be larger, otherwise it will evaporate quickly and water will be needed. But in the other two seasons, the temperature is relatively low. At this time, after transplanting vegetables, you don't need too much water, otherwise the soil temperature will drop, and you just need to pour it in the place where vegetables are planted.

Step 3 plant. In early spring, the price of vegetables is getting lower and lower, so we must improve the yield in the early stage, and proper planting can be more dense. The winter festival is the opposite. At this time, vegetable prices are getting higher and higher. The front grows better, and it is a little thinner when planting. In autumn, the temperature is still relatively high. At this time, plant it a little deeper to avoid the root system being affected by sunlight. Then in the cold winter and spring, the soil temperature is relatively low. At this time, the depth of planting should be slightly shallow, which can make the roots more breathable.
