How to choose the number of vegetable greenhouses to be planted? This problem should be a problem that many farmers are very concerned about, because the practice proves that it is not a lot of colonization, the economic benefits are good, but the appropriate number of colonization is needed.
Vegetable growers in greenhouses, especially in vegetable farms outside Shouguang or in areas where planting techniques are relatively backward, many vegetable farmers prefer dense planting. The reason is simple. One more seed will receive one more. However, the vegetable farmers who are actually a lot of sheds are tired of dealing with all kinds of diseases and insect pests in the greenhouse. And the commodity rate is not high. The sale is not good. The work has been done a lot but the news is not very good.
Many vegetable farmers like to use the amount to benefit. Most of them think that the number of colonization is much. Natural production is also high. However, in actual operation, if the management work after dense planting increases. Seedling costs increase and are prone to disease, and the commodity rate is low.
Then it is more appropriate to plant a colon per acre. According to experience, the number of plants per acre is generally around 2000, which is more suitable for square seedlings without squares. Here is an example of greenhouse tomatoes.
For example, your greenhouse is 80 meters * 7 meters of calculation is to plant 1680 is more appropriate. Nowadays, many colonizations are mostly doubled. That is, the number of plants in the 80*7 m greenhouse is between 2,800 and 3,000. The drawback is that the tomatoes in the small line basically do not see the sun, only a small line of nutrients, no nutrients. The corridor inside the big row is covered by the leaves. Farming operations are inconvenient. Poor ventilation is prone to disease. And because there are many leaves sprayed in the dense plant spray.
If planting is carried out at a distance of 90 cm from a plant spacing of 40-45 cm, not only can the seedling cost be saved. The workload has also been reduced a lot. And because the colonization is relatively thin and ventilated. Good light transmission. The natural commodity rate is just fine.
Many vegetable growers have always believed that such production will decrease. But the actual experience tells us. Not only will the output not decrease, but the benefits will be better than the dense planting. Therefore, vegetable farmers should take a look at the planting and learn more. Give up the original conservative concept. How can we reduce the workload and increase the rate of goods, this is the purpose. As for the market, if the commodity rate is low, the benefits will be even worse.
