How to grow bananas planting methods and matters needing attention

Everyone is familiar with eating bananas, so growing bananas is different, because on the one hand, we lack land to grow, and on the other hand, we lack experience and technology in planting, so most people are banana eaters, not banana growers. But after a long market test, although the current market price is not very high, but the demand is stable. So it should make sense to grow bananas.

How to grow bananas

1. Land selection and planting: it is ideal to choose plots with mild frost, good ventilation and open terrain. Spraying new high lipid membrane after planting can shorten the slow seedling period, quickly adapt to the new environment and grow healthily. The amount, period and times of banana fertilizer application must be determined according to the soil fertility, the level of yield, the law of growth and development and the properties of fertilizer. The method of irrigation is adapted to local conditions. Irrigation should be done frequently and in an appropriate amount.

2. Cultivation techniques of banana:

① plant management: removing buds; there are many sucking buds on the corm of the mother plant, so removing buds can reduce the consumption of nutrients. Broken buds; bananas reproduce asexually, so they can only leave the female flowers at the base after budding, and then the neutral flowers and male flowers can not bear fruit. The upper part of the bud is cut off with a knife, allowing nutrients to be concentrated for fruit development. Dig the old banana head; dig the old banana head in time, so as not to produce a large number of large leaf buds, consume nutrients and increase the difficulties in management. Cut off buds and remove banana head wounds should be smeared with callus anticorrosive film to prevent the invasion and infection of diseases and insect pests.

② promoting strong fruit: spraying Zhuangguotiling in female flower bud stage, young fruit stage and fruit expansion stage can thicken fruit pedicel, increase nutrient transport, prevent falling flowers, improve pollination ability, increase fruit setting rate and accelerate expansion speed. Due to the size of the tree hanging fruit, the load of the tree is out of balance, which affects not only the balanced income, but also the health of the orchard tree. Therefore, it is necessary to brush around to promote Huawang No. 1 in the period of flower bud differentiation every year, increase the fruit setting rate, inhibit shoot growth, and completely balance the size of the year.

Banana planting methods and matters needing attention

The main results are as follows: 1. the best propagation time of banana is from mid-March to early April, and the specific time depends on the source of seedlings. Autumn planting should be carried out from late August to mid-September.

2. The best growing soil: the banana root group is delicate, the selection of soil is strict, the clay heavy soil with poor aeration structure or poor drainage is extremely unfavorable to the development of the root system. The sandy loam with clay content {lj} lt;40 {bf} and groundwater level below 1m, especially alluvial loam or humus loam is suitable.

3. Growth humidity requirements: bananas prefer humid climate

4. The best growth temperature: the growth temperature of banana is 20-35 ℃, the most suitable is 24-32 ℃, and the lowest should not be lower than 15.5 ℃.

5, the best growth light: bananas like sunny environment.

6. Spread fertilizer:

Banana needs a large amount of fertilizer for growth, and its root system is developed but its distribution is shallow. It is particularly sensitive to fertilizer. Nitrogen fertilizer can promote early flowering of banana and has a significant effect on increasing yield. Potash fertilizer is a necessary component for the synthesis of pseudostem and leaf fiber: banana needs the most potash fertilizer, followed by nitrogen fertilizer, followed by phosphorus fertilizer, and the ratio of nitrogen, phosphorus and potassium is 4:1:14. The K / N ratio of the varieties with tall culms was low, while that of the varieties with short culms was higher, and the K / N ratio was lower in the early stage and higher in the later stage.

7. Watering points:

Banana water demand is larger, generally require monthly rainfall of more than 100 mm, less than 50 mm belongs to the dry season, banana due to lack of water and bud period prolonged, fruit index short, per unit yield is low. The rainfall in South China is uneven, high temperature is often accompanied by rainy, low temperature is accompanied by drought. The rapid growth period of banana leaves is not only the most exuberant period of plant growth, but also the period of the most water demand. Supplying enough nutrients and water in the high temperature season can promote the expansion of leaves and plant growth, early budding and increase the yield of banana. Long-term drought led to slow growth of banana plants, yellowing, withering and drooping of leaves and atrophy of pseudostems. In the period of flower bud differentiation, fruit comb number and fruit index decreased, and fruit index became shorter.

The yield of banana

Generally, the yield of banana is about 2000-2500 kg per mu. Good planting techniques and varieties can improve the yield of banana, and scientific fertilization is particularly important. For example, Liang Zhenfa, a banana farmer in Qianwu Town, Doumen District, Zhuhai, planted bananas with an average yield of nearly 6000 jin per mu at a fertilization cost of less than 600 yuan. Liang Zhenfa believes that scientific fertilization is the top priority of banana management. "too much fertilizer will lead to waste, not only increase costs for no reason, but also burn seedlings; if there is less nutrition, it will reduce production. The most important thing is to grasp the right quantity. "

How to keep bananas for a long time

1. Many people will put bananas in the refrigerator for cold storage, which will cause the banana flesh to turn dark brown and affect the taste. The correct way is to rinse the whole bunch of bananas with clean water several times to reduce the corrosion of ripening agents. Under the same external conditions, washed bananas can be stored for 5 or 7 days without deterioration.

2. Then, dry the surface of the banana with a clean rag to ensure that the skin is dry without moisture. Finally, wrap the bananas with some old newspapers and put them in a ventilated and cool place indoors.

3. It should be noted that there is also a knack for placing bananas. The pressure surface is too large, which will lead to the blackening of the banana surface in contact with the table, and then rot. When the whole bunch of bananas is large, it is best to let the protruding side face up, and when the amount is less, then put it on one side and eat it as soon as possible.

4. If there are conditions, it is best to hang the banana up to reduce the pressure area and prolong the preservation time. With the above tricks to preserve, I believe that your banana can be "beautiful" for longer.

There is still more room for improvement in banana production through technical improvement, but banana preservation has always been a very important part of banana planting management, which is not only related to the quality of bananas. it's also about the final market profit. So it is the content that we should all pay attention to.
