If you want to make a steady profit from growing corn in a greenhouse, what should you pay attention to?

Corn can germinate normally when it absorbs 48-50% of the dry weight of the seed. When the soil moisture in the 5 to 10 cm soil layer reaches 60% of the maximum water holding capacity in the field, the needs for seed germination can be met. When the soil moisture is about 70% of the maximum water holding capacity in the field, the seedlings will emerge quickly and the seedling emergence rate will be high. When the soil moisture reaches more than 80% of the field capacity, the seeds will easily rot due to excessive soil moisture and insufficient air, affecting seedling emergence.

Use ultraviolet rays from the sun to kill bacteria on the surface of seeds, improve the ventilation of the seed coat, facilitate the formation of permeable nutrients inside the seeds, promote enzyme activity, discharge carbon dioxide and various wastes, thereby enhancing Improve seed vitality, break dormancy, improve seed germination potential, and enable seedlings to emerge 1-2 days earlier.

Selecting chemical fertilizers is also very important. You should choose fertilizers produced by large factories, that is, fertilizers with eyes that are granulated in high towers. The quality of this fertilizer is good. The key is that it is not fake. If it is fake, the cost will be higher than if it is not fake. In recent years, our local area The annual nitrogen content used is 26%, the phosphorus content is 12%, the potash content is 15%, and the total content is 53%. In short, the potassium fertilizer is more than the phosphorus fertilizer. , to prevent corn from losing fertilizer in the later stages of growth and development, resulting in reduced yields and reduced economic benefits.

In rural areas, a few acres of land does not have much economic benefit. If it can be transferred to a large amount of land, a model of combined planting and breeding can be developed, 1. Planting of multi-flowered Chinese medicinal materials + bee breeding 2. Planting of rapeseed + Cauliflower Festival Sightseeing + Bee Breeding 3. Fruit Forest + Understory Breeding

According to the current market price, corn is 0.8 yuan to 1.2 yuan per catty. If the yield is high, the yield will be 1,200-1,600 catties per mu. If the land is contracted to grow corn The economic value is not high!

According to the current market price, it is still profitable. The previous swine fever caused various prices to rise. If it is a plain area, it may be possible to grow it, and relatively speaking, it can be done by machine on a large scale, but if it is like the south, The land here is uneven and hard, so we won’t consider it.
