How much income can you get from planting out-of-season vegetables in vegetable greenhouses?

Walking into the vegetable greenhouse of vegetable farmers, a hot and humid air came to my face. The tomatoes on the shelf are delicate and the vegetable farmers are busy picking them. Catch up with the festival, the price of vegetables has gone up again, and my aunt is certainly willing to sell it at a good price.

Traditional agriculture can't earn much money on an acre of land, so it's good to make a living. Many farmers build vegetable greenhouses in the village to earn some hard money. Don't underestimate this vegetable greenhouse. A good annual income of 40 thousand to 50 thousand is not a problem, not bad at all compared with office workers.

Vegetable farmers said that a vegetable greenhouse with an acre of land can earn at least 30,000 yuan, and a crop of vegetables can earn 1 10,000 to 20,000 yuan, but there are also uncontrollable risks such as natural disasters or market demand, but overall it is better than working away from home.

The advantage of vegetable greenhouse is that it is planted out of season, early spring and late autumn, and the whole market price is relatively high. Using this off-season time difference, the income is often considerable, and it can be said that the "money" scene is infinite.

Planting techniques:

1, build a greenhouse

First of all, we should choose areas with flat terrain, convenient water sources, less wind and plenty of sunshine to build greenhouses, preferably in plain and hilly areas. Greenhouse is mainly divided into winter-warm greenhouse and spring-autumn greenhouse, in which winter-warm greenhouse is planted in winter, and spring-autumn greenhouse is suitable for planting in late autumn and early spring. After the greenhouse is completed, it needs to be disinfected. It can be disinfected by high-temperature stuffy shed or chemicals, which is very effective for pest control. In the first half of planting, you can spray hundreds of dust agents into the greenhouse and then smoke it with chlorothalonil smoke agent. After about a week, carbendazim can be sprayed on the ground, which can achieve excellent disinfection and sterilization effect.

2. Soil preparation and fertilization

Nutrient soil should be prepared in the greenhouse before planting, which is the key point of vegetable growth. Generally, fertile soil should be selected when planting, and organic fertilizer and inorganic fertilizer should be applied together with Woye water-soluble fertilizer or Woye bacterial fertilizer. Pay attention to the time and method of fertilization. Fertilization should be carried out one month before planting. Pay attention to the amount of fertilization. Sprinkle fertilizer on the soil and turn it over to make it fully mix with the soil. In addition, before fertilization, the decomposed fertilizer is fermented and then applied to avoid producing toxic gas in the soil and endangering the growth of lettuce.

Step 3 Choose vegetable varieties

Off-season vegetables can't grow all vegetables. Varieties with cold tolerance, strong disease resistance and early maturity should be selected to reduce the influence of low temperature on vegetables, such as zucchini, tomato, pepper, eggplant, cucumber, towel gourd and so on. In addition, vegetables such as spinach and cabbage can be planted in winter, and the yield will be higher.

4. Tian Tuan management

Grasping the nest and applying organic fertilizer in the pit when growing vegetables can improve the survival rate. In addition, the seedlings should be watered in time after planting to maintain soil moisture. Different vegetables have different needs for water, so watering times should be controlled to meet the growth needs of different vegetables. It is also necessary to loosen the soil and weed regularly to prevent weeds from robbing nutrients and affecting vegetable growth. Loosening soil can promote the growth of seedling roots more smoothly. It is also found that the diseased plants should be removed in time to avoid the spread of pests and diseases, auxin and growth inhibitors should be sprayed reasonably, and pest control should be strengthened.

5, heat preservation, moisturizing and cold work

The key point of anti-season vegetable planting is to do a good job of heat preservation, moisture preservation and cold protection. Freeze injury may occur under three conditions: lack of water for seedlings, low ground temperature, low night temperature, insufficient root nutrition and weak cold resistance. Therefore, in view of these situations, it is necessary to keep soil moisture at all times; Regularly loosen the soil to prevent soil hardening; Spraying foliar fertilizer regularly to increase plant nutrition; Regular ventilation can reduce the emission of toxic gases such as carbon dioxide, and also make vegetables adapt to the external temperature; Cover with multi-layer plastic wrap at night to reduce the heat dissipation in the shed.
