Pink banana, also known as milk banana, glutinous rice banana, rice banana, southern banana, egg banana, plant growth strong, more drought-resistant, cold-resistant, wind-resistant, management is more rough, high yield, general plant yield 20 to 25 kg, individual high yield 45 to 50 kg. There are two kinds of fruits: green plantain and white plantain, and green plantain has higher yield. After ripening, the skin color of pink plantain is yellow or pink-yellow, with thin skin, and the flesh is smooth, sweet, yellowish-white, and has the taste of milk, so it is called milk plantain. Pink plantain is a very popular local marketing varieties in recent years, the planting area is expanding.
2, garden selection
Planting plantains need to choose not planted plantains, plantain garden over the mountain incense, soil loose, well-drained sandy loam to clay loam, should not choose too sandy soil. It is good to plant planting plantain sporadically, the pond bank, five sides of the land, in front of the house, behind the house, the soil layer of the hill is a good place to plant planting plantain, can also be used as banana plantation windbreak forest planting. The paddy field planting must be high bed deep ditch, it is best to plant a row of rows, the serious disease area can be intervals of 2 to 4 rows of bananas between the planting of a row of plantain.
3, pink plantain seedling selection
Pink plantain is not suitable for seedlings with sucking buds, because at present there are Fusarium pathogens all over China. When the sucker bud seedling pink banana growth potential is weak (mainly in the flower bud differentiation) will occur when the wilt disease, resulting in loss of harvest. Pink plantain orchards with histocultured seedlings can usually have 60% or more of the harvest. It is generally best to use seedlings with 5 to 7 leaves in age; seedlings that are too large and slow to resume growth after planting are generally required to have 1/3 to 1/2 of their leaves cut off. Pink plantain varieties to wide pink 1 better, the average plant yield can reach more than 25 kg.
4, pink plantain planting time
Pink plantain can be planted throughout the year, cultivation help recommend spring planting, summer planting, fall planting (September to October) is better. Such as the Guangzhou area, spring planting (2 to April) to collect early summer bananas (5 to July); summer planting (5 to July) to collect autumn bananas (8 to November), plantain mid-autumn festival price is higher; autumn planting (8 to October) to collect spring bananas, winter planting (November to January) to collect spring and summer bananas.
5, pink plantain planting density
Because the pink plantain plant is taller, monoculture planting planting spacing of 3 meters × 2.2 meters to 3 meters × 2 meters, 100 to 110 plants per acre; lodging cultivation should be appropriately sparse planting, 90 to 100 plants per acre; kan dike planted as a windbreak can be denser.
6, banana garden management
Pink banana growing more weeds in the early stage, artificial weeding or mulching weeding, to reduce the grass and bananas to compete for fertilizer and insect pests occur. After becoming a plant, especially after the buds should be staked to prevent the wind, or pull the tape to connect with each other, chained to resist the wind. Pink plantain is also very sensitive to water requirements, the water table must be less than 60 centimeters, otherwise, the plant grows poorly and is prone to complications of physiological diseases.
7, fruit thinning
Pink plantain comb number generally 12 to 15 combs, stay 8 to 10 combs, excess to be thinned out, otherwise the fruit spike on the big under the small, the tail comb fruit difficult to full, can be sprayed with abundant fructose to lengthen the lower part of the fruit, the harvest period to be a little longer.
8, pink banana fertilization
such as soil thin banana garden should be applied to the base fertilizer, the best per plant with soil fertilizer 10 to 20 kg, can also be used chicken manure, pig manure, peanut bran and other organic fertilizers, composted and rotted. Also available 150 to 200 grams of compound fertilizer, 150 grams of potassium sulfate, calcium superphosphate or calcium magnesium phosphate 500 grams. Fertilizer should be applied early, spreading should be within the distribution of the root system, adult plants (20 ~ 30 leaves) fertilizer should be used to dilute drenching, the entire reproductive period of fertilizer per plant: urea 500 ~ 750 grams, divided into 6 ~ 9 times; sulfate of potash 750 ~ 1,000 grams, divided into 5 ~ 7 times; 500 grams of composite fertilizer, 250 grams of potassium dihydrogen phosphate, divided into 5 ~ 7 times. Fertilizer should not hurt the roots, so as not to induce yellow leaf disease. Pink banana in acidic soil is prone to the symptoms of magnesium deficiency, through the application of magnesium sulfate can alleviate the symptoms of magnesium deficiency. Available banana special compound fertilizer, distinguishing between pre-fertilization and post-fertilization, the entire reproductive period with 2.5 to 4 kg. At present, there are also views that heavy fertilizer will induce Panama disease, less fertilizer banana garden can be harvested ninety percent, more than only six or seven percent.
9, pink plantain buds
If it is sporadically planted pink plantain or grouped seedlings of the first buds when the incidence rate is not higher than 5%, you can stay in a late fall to early spring drawn sucker buds for the successor plant. The mother plant should be in bud, or about to bud, and the early buds should be removed when the plant is about 30 centimeters high after emerging from the soil. In addition to buds, pay attention not to hurt the root system of the mother plant, with a sickle along the ground to cut off the sucker buds, and use kerosene to destroy the growing point. You can also interrupt the buds when they grow to 50 to 70 centimeters high to inhibit bud growth. The banana garden with more yellow leaf disease plants is best not to leave buds.
11, pink banana harvest
Pink banana harvest requires high maturity, the fruit spike should be left until the banana fruit is completely complete, and even the banana fruit is full down when harvested. Harvesting period in the summer is generally 85 days to present buds, break buds more than 70 days, sometimes in winter to hang fruit up to 180 days. Delayed harvest yield can increase 10% to 20%, the price is about 10% higher, income can increase by 30%.
