I. Breeding and Breeding Kay-hsing has successfully selected Kaohsiung No. 1, No. 2 and Kaixiong Qiaojia and other fine varieties for cultivation of seedlings.
Second, planting and cultivating management The best time for planting field cultivation is spring planting. In combination with the conditions of the banana base soil in Gengma County, the method of planting is planting and planting in pit ponds. The paddy field adopts trenches and requires the soil to be ploughed after deep plowing, one line and two lines, with a depth of 0.5 meters, a width of 0.3 meters, a length of 100 meters, and a secondary drainage ditch to facilitate irrigation in the dry season and drainage in the rainy season. Planting specifications are based on 1.7 2.2 meters wide and narrow rows, 176 plants per acre; dry land is used for planting ponds, planting specifications are 1.7 2.6 meters wide and narrow, and 150 plants are planted per acre.
Fertilization after planting should adhere to the "diligent application, thin application, and key application", and after 2 to 3 weeks of planting, use diluted manure or a small amount of quick-acting fertilizer to flush 5 kilograms of water and apply it once every 7 to 10 days (on a sunny day, 10 to 15 centimeters away from the head of the banana plant, until it reaches the core, and as the plant grows, it gradually expands the scope of fertilization along the crown surface. In addition to daily topdressing, it is necessary to re-apply two fertilizers in conjunction with cultivating soil. The first time is to change the bar fertilizer, which is carried out from late April to early May. Each of the plants applies 0.3 kg of phosphate fertilizer and potassium fertilizer and 3 kg of gray manure. The second is to change the fruit fertilizer, in the beginning of autumn or in early July in late July, each plant applied ash manure 5 kilograms, compound fertilizer 0.5 kilograms.
After planting, with the growth of the plant, shoots from the roots should be promptly removed, and the core of the fruit should be harvested. According to the growth of the plants, the number of suitable fruits should be determined and the buds should be cut off to ensure sufficient supply of plant nutrition.
Third, prevent banana diseases and insect pests such as banana bunchy disease, mosaic heart rot, leaf rot anthrax and line disease, etc., pay close attention to forecasting and prevention work, to prevent large-scale occurrence of pests and diseases. In particular, banana mosaic heart rot and bunchy top disease should be prevented. In combination with spray fertilizer, aphids should be sprayed with pesticides such as 1.5% Pole 1500 times liquid or 2.5% kungfu 3000 times liquid to completely eradicate the transmission medium; When the diseased plant was excavated with the sucker, the plant was excavated or burned, and 600 times liquid was used to force the virus and bacteria to spray and prevent. In order to improve plant immunity and protect the growth of healthy plants, it should be carried out in a severe banana garden with a 1:1:10 Bordeaux mixture and 50 grams of trichlorfon to brush stems of bananas to prevent stem rot and weevils. When the old leaves of bananas are spotted with water-stained lesions, they are sprayed with 1200-times liquid spray with 25% of the enemy's strength in time. In the medium-term round, 20% of the enemy's strength is used to disperse 1,000 times or 30% of Ai Miao's 1500-times. 30% Ai Miao 1500 times liquid or 25% potential gram 2000 times liquid prevention, once every 15-20 days, once every 2-3 times.
Fourth, timely harvest According to different varieties, planting levels and banana maturity, timely harvest.
