较系统地研究了香蕉组培苗的营养与施肥,试验方案包括了NPK13种用量水平、10种不同NPK配比和中微量元素混施.试验结果表明,在一定的NPK施肥基础上.再增施NPK均能获得不同程度的增产,其中增施N的增产幅为4.7%-15.0%,增施P、K的分别为3.4%-15.1%和6.6%-12.6%.增N有利于植株增高、茎围增粗、长叶增快和提早吐蕾;增P对植株增高和提早吐蕾也有一定的作用;增K主要有利于茎围增粗,但在高N高P下增K也同样具有增N的多种效果.增K的另一效应是延缓吐蕾期而使吐蕾期较集中一致,这有利于田间管理和收获;施用中微量元素的增产效果显著,同时也改善和提高了果实品质.应提倡应用和推广.
The nutrition and fertilization of banana tissue culture seedlings were systematically studied. The experimental plan included NPK13 levels, 10 different NPK ratios and medium and microelements. The results show that, based on the NPK fertilization. With the increase of NPK, the yield could be increased to some extent, of which, the increase of N was increased by 4.7% -15.0% and the increase of P and K was 3.4% -15.1% and 6 respectively. 6% -12.6%. Increasing N was beneficial to plant height, thickening of stem circumference, faster leaf growth and earlier sprouting. Increasing P also had some effects on plant height and early sprouting. Increasing K was mainly conducive to thickening of stem circumference, but increased at high N The increase of P under P also has many effects of increasing N. The other effect of increasing K is to delay the spatting stage, which makes the spittable stage more concentrated and consistent, which is beneficial to management and harvest in the field. The application of trace elements has a remarkable yield increasing effect, and also improves and improves the fruit quality. Should promote the application and promotion.
