How to grow bananas in a greenhouse instead of in the tropics?

Now, banana trees can be planted not only in tropical areas, but also in greenhouses. The planting techniques are as follows:

First, dig planting pits and apply base fertilizer.

The minimum planting distance of the planting pit is 2m. The depth of the planting pit should be similar to the planting depth before the separation of seedlings and soil. After digging the planting pit, mix 10 kg of retted farmyard manure and 0.25 kg of compound fertilizer evenly and apply them into the planting pit as base fertilizer.

Select the new seedlings with many green leaves, developed roots and no diseases and insect pests as the new seedlings to be transplanted, and use tools such as shovels to separate the roots from the original banana roots to minimize the trauma to the surface of the seedlings. After the new seedlings are separated, put the roots in Guoguang rooting agent (5- 10kg water /2.5kg) for 5 minutes, and then put the banana seedlings into the planting pit to cover the soil, which should be filled.

Second, the daily management of the greenhouse

1. Water and fertilizer management

Banana trees have high water content, shallow root distribution and are not drought-tolerant, so the soil must always have water supply. During the vigorous growth period, water frequently, but be careful not to accumulate water.

Topdressing 5 kg of high-quality organic fertilizer and 0.2 kg of ternary compound fertilizer every two months. It should be noted that the demand for nutrients for bananas usually increases with the increase of leaf stage, especially when bananas enter leaf stage and fruit stage, which is an important fertilization period for banana trees. Appropriately increase the amount of fertilizer to achieve the balance of fertilizers such as nitrogen, phosphorus and potassium.

2. Temperature management

Banana trees belong to tropical and subtropical plants and like high temperature and humidity. When the temperature is lower than 5℃, banana leaves may freeze, and when the temperature drops to 0℃, all plants on the ground freeze to death. Therefore, it is very important to plant banana trees in greenhouse and do a good job in winter cold and antifreeze. Specific measures are as follows:

① Irrigation: Irrigation in time before the arrival of frost, so as to improve the soil heat capacity and play a role in preventing cold and freezing.

② Fertilization: According to the growth status of banana trees, apply winter fertilizer before the first frost to increase the amount of available phosphorus and potassium fertilizer. Each plant was treated with 15 kg farm manure, 200 g calcium superphosphate and 150 g potassium sulfate.

③ Smoke: In the forecast of cold weather at night, straw, straw and sawdust are piled into a pile, each pile is 5 kg, evenly distributed, and the haystack is lit to make a small fire, but the smoke fills the air.

④ Warm-up: After winter, when the greenhouse has heating conditions, it should be warmed up in time to increase the temperature in the greenhouse and ensure that bananas are not frozen.

These are the two main points of planting bananas. I hope I can help you.
