When will the perennial herb banana taro be planted? When will you collect it? How is the planting benefit? How do you plant it?

Banana, also known as ginger, banana, banana lotus root, banana bud, banana bud, Xiangzhu, is a common Chinese herbal medicine in most parts of our country, because of its wide range of uses, set ornamental, edible, medicinal, feeding, brewing in a body and is widely cultivated, when is the banana planted? When will it be closed? How about planting benefits? How?

Planting time:

It is generally planted in February to April in spring when the temperature is stable above 12~14℃.

Harvest time:

From the middle and late November to December, when the temperature drops obviously and the first frost occurs, and the dried banana appears on the ground, the stem and leaf are cut off, the rhizome is dug out, the fibrous root is removed, and the banana can be processed after washing. In case of frost, harvest before frost. The fresh taro reserved for seed should be selected without damage, no disease and insect pests, full and healthy, thick and complete bud, strong vitality, single weight of 50~ 150g, can be buried directly with soil, or can be spread for 3~4d and then buried with soil, covered with banana stem and leaf, straw or other hay, etc., covered with film for heat preservation and antifreezing before frost and snow damage, and when the temperature rises in spring, the tuber will germinate and grow into seedling.

Benefit analysis:

Planting banana taro is simple and extensive, with less investment and quick effect. It is a quick way to get rich. In 2017, Quxi Village, Quxi Township, Liancheng County planted more than 70 hm2 of taro, yielding 45~90t/hm2 of fresh taro, purchasing price of fresh taro 1.0~1.2 yuan/kg, and output value of fresh taro 45,000 ~ 90,000 yuan/hm2. The starch is extracted by processing, and the starch produced per 100kg fresh taro is 15~16kg, the market price is 12~14 yuan/kg, and the output value is between 90,000 yuan and 165,000 yuan/hm2. It is deeply loved by farmers.

Use value:

1. The banana is a good material for beautifying the courtyard because of its luxuriant stems and leaves, long viewing period and simple management. Its root-like tuber is sweet, light and cool, with the effect of clearing heat and removing dampness, calming the nerves and lowering blood pressure. Its roots and flowers can also be used as medicine. Tubers are rich in starch, which can be boiled or extracted. It is an excellent starch processing raw material.

2, potato starch particle size is large, gelatinization temperature is low, paste transparency is good, amylose content is high, film formation is good, its molecular weight is very large, has good application properties, is a new source of high-value starch; starch can be directly processed vermicelli, vermicelli and other food and food ingredients, but also can be used to produce monosodium glutamate, wine, production of oral and injection glucose, sorghum maltose and other starch-like sugars, and a variety of non-staple foods such as lotus root starch;

3. In the textile industry, banana starch sizing is better than grain starch sizing, which has the characteristics of high adhesion and good smoothness; banana starch and stem fiber can also be used for feed, paper making, shoe making, hat making, clothing and stationery.

4. The banana residue and stems and leaves can be used as breeding feed to promote the development of breeding industry. The application and market prospect of banana is broad.

High-yield cultivation techniques:

1. Land selection and preparation

Canna has strong adaptability to soil, likes moist and fertile deep soil, is more drought-resistant, avoids waterlogging, and should choose plots with sufficient sunshine, sunny wind and good drainage. Most areas in southern China can be planted regardless of altitude. It is best to use gentle slope sandy loam with deep soil layer, loose fertile soil, good drainage, neutral acid value and rich organic matter and humus, and also adapt to grow in fertile clay soil. It can be planted in rice fields, hillsides and remote plots in large areas, or scattered in front of houses, behind houses, beside ditches and other fields.

Winter ploughing should be carried out after suitable plots are selected for high yield cultivation to promote soil ripening and fragmentation. 1 500 kg/hm2 Ca Mg P fertilizer and 30t/hm2 organic fertilizer were applied as basal fertilizer in spring. The soil preparation should be deeply ploughed and carefully cultivated, the soil crushed and leveled, and the fertilizer should not be exposed to the soil surface evenly. It is advisable to make high ridges, the ridge height is more than 30cm, the ridge width of single row planting is 70cm, the ridge width of double row planting is 110cm, the ditch width is 30cm, and the drainage ditch is opened around to prevent ponding.

2. Seedling selection treatment

Tuber propagation is mostly adopted in production. Seed taro is buried in soil and covered with straw in autumn and winter of last year to keep warm and freeze. When the temperature rises in spring and tubers sprout and grow 2~4 leaves, strong seedlings without diseases and insect pests are selected for transplantation into the field. After seedling emergence, taro seedlings can be soaked in 800 times solution of carbendazim for 5~10min to improve disease resistance.

3. Planting density

Planting row spacing 60~70cm, high ridge cultivation or hole cultivation, planting density of 15000~19500 plants/hm2. When scattered planting is carried out on the edge of the field, in front of the house and behind the house, attention should be paid to applying more decomposed organic fertilizer as base fertilizer and watering enough water after planting.

4. Cultivation

In the early stage of growth, weeds should be cultivated in time to avoid competition for nutrients and space between weeds and banana. During the whole growth period, the soil should be cultivated for 2~3 times, and the soil in the furrow should be cultivated on the ridge surface to facilitate the growth of banana. According to the growth characteristics of the underground stem of banana, it is deep in the early stage and shallow in the late stage, so as to speed up the differentiation and expansion of the root tuber and prevent lodging.

5. Reasonable fertilization

Fertilizer application is the key measure for high yield of banana. On the basis of applying sufficient base fertilizer, rational topdressing should be applied. 75~150kg/hm2 of 45% potassium sulfate compound fertilizer is applied in seedling stage; 450~750kg/hm2 of 45% potassium sulfate compound fertilizer is applied in middle stage combined with intertillage soil; phosphorus and potassium fertilizer are mainly applied in later stage, and partial application of nitrogen fertilizer is avoided; 225~450kg/hm2 of potassium sulfate, 750kg/hm2 of calcium superphosphate, or 750~900kg/hm2 of 45% potassium sulfate compound fertilizer is applied before flowering. Fertilization fertilizer should be evenly applied to the left and right sides of the root, in order to facilitate full absorption of nutrients and plant balance 3.3.4 scientific water management. Canna taro growth period needs more water, but drought resistance is strong, avoid waterlogging, field ponding easy to lead to water rot roots dead seedlings. The principle of water management is to irrigate once every 15~20 days in drought, pay attention to watering in time after fertilization, do not irrigate and soak, and do a good job of drainage and waterlogging prevention in rainy season.

6, cut flowers

In order to avoid nutrient consumption, the flowers should be cut off in time when flowering, so that nutrients can concentrate on supporting the growth of underground stems and increase yield.

7, pest control

The resistance to diseases and insect pests of banana is stronger, and there are few diseases and insect pests, mainly including banana plague, bud rot and stem rot. Carbendazim and thiophane can be used to control potato plague, while chlorothalonil and Fuxing No. 1 can be used to control bud rot and stem rot. Aphids sometimes occur in the early and middle stages, which can be controlled by pesticides such as dimethoate and imidacloprid.
