(1) Selection of origin
The place of origin is chosen to have an annual average temperature above 20°C and a multi-year average of extreme minimum temperatures above 2.6-6.2°C; the soil has a high organic matter content and a pH of 6.0 to 7.0. Stay away from factories with sewage, waste residue, and waste gas emissions. The environment is pollution-free. Farmland soil, agricultural irrigation water, and air quality meet the environmental quality standards of green food production areas.
(2) Fertilizer selection and planting pit design
① Base fertilizer composting
Two months before planting, use pig and cow manure, pond manure, turf manure and an appropriate amount of compound fertilizer to pile together. After decomposition, apply 10 kilograms per pit as a base fertilizer for planting.
② Plow and harrow the ground
Before planting, plow and harrow the banana orchard twice to create a loose soil condition for the growth of the root system.
③ Digging holes at fixed points
Before planting, draw lines at fixed points according to the planting row spacing of 2×2 meters, and dig planting pits with a length, width and depth of 0.4 meters each. About 165 plants are planted per acre. (or 2×2.5 meters, 130 plants per mu)
④Return to the pit
First, place 10 kilograms of decomposed base fertilizer at the bottom of the planting pit, and add 0.25 kilograms of compound fertilizer. Mix well and then cover with soil. The soil should be returned to the soil pile 10-20 cm above the ground to prevent sinking and water accumulation after planting.
(3) Seedling selection and planting time
①Seedling selection
Choose seedlings with dark green leaves, well-developed root systems, 15-20 cm tall, 5-6 new leaves, and no pests or diseases.
②Planting time
Spring planting can be done in mid-to-late February, and autumn planting can be done in September.
③Planting method
Classifying banana seedlings according to size and planting them in zones can facilitate management. When planting, make a small opening in the planting pit, place the seedlings gently in the pit, and bury the banana head in the soil about 10 cm deep. The incision of the seedlings faces one side. After planting, lightly step on the planting pit, pour enough planting water, and cover with straw.
(1) Fertilization Fertilizer application is mainly based on bio-organic fertilizers, supplemented by chemical fertilizers, and scientifically matched with nitrogen, phosphorus, and potassium. Fertilization adopts the principles of early promotion, middle attack, and late supplementation. Fertilization is applied frequently in the early stage, heavy application of fetal fertilization in the mid-term, and supplementary application of fruit-enhancing fertilizer in the later stage. Fat.
(2) Weeding Banana fields should have high borders and deep ditches to facilitate drainage, lower the groundwater level, and allow for irrigation. During the period of vigorous growth, it is necessary to always maintain a shallow water layer in the furrows so that water can be poured early and late in the dry season and the banana furrows can be well covered. Banana is a shallow-rooted plant. When weeding, it should be removed by hand. It is taboo to step on the border or damage the roots by hoeing.
(3) Leave buds and remove buds Cut off the first sucking buds. After the second or third sucking buds are drawn, be sure to keep 1-2 suitable sucking buds, and remove all the remaining sucking buds.
(4) Broken buds After banana budding, pay attention to field inspection. When the top 1-2 combs of the banana axis are not strong, break the buds on a sunny afternoon to reduce the loss of sap. When the wound sap stops, use 500 times of carbendazim and other fungicides. Paint the wound. (5) Water spraying and drainage and irrigation If drought occurs after planting, water must be poured and the medium and micro irrigation method integrating water and fertilizer should be used. Keep the soil on the border and hole surfaces moist to facilitate root recovery and growth; be careful to remove accumulated water on rainy days. From September to March of the following year, the border surface is covered with straw to keep warm and moisturizing; especially the tissue culture seedlings planted in spring grow to the stage of large leaf and fruit development (July to December), which is a critical period for water supply. , requires a lot of water, and the soil on the border should be kept moist, otherwise the yield will be affected in case of drought. Irrigation methods can include shower irrigation, drip irrigation, sprinkler irrigation, etc. Stop irrigation 15 days before harvesting to extend the storage and transportation period.
