Banana important during fertilization

Banana nutrient demand generally increases leaf stage increases. 18 to 40 banana leaf stage of growth and development is good or bad , on the yield and quality of banana play a decisive role , so this period is important fertilization of banana . This period can be divided into vegetative growth and flower bud in the late period of two re-applied ,pressure sprayers should be most concentrated in these two periods fertilizer application .

① in the late vegetative growth ( 18 to 29 leaf stage ) , that spring planting banana planting of 3 to 5 months after planting and summer perennial planting banana banana shoots sprouting given after 5-9 months. From the leaf look, just pumping by the middle of this period ( this time just out new leaves mostly curved shape like Huwei ) to enter the big leaf 1 to 2 . This period is at peak vegetative growth , nutrient requirements are very strong , most sensitive , banana plant growth and development was good or bad , by the abundance or shortage of fertilizer supply is determined , if this was re-applied fertilizer , banana plants to obtain sufficient nutrients, can long evening stem diameter banana leaf large strains for efficient assimilation , the accumulation of a large number of organic compounds, is to lay the material foundation for the next stage of flower bud .

② flower bud differentiation stage ( 30 to 40 leaf stage ) , ie after planting spring planting banana 5-7 months after planting and summer perennial planting banana banana shoots sprouting given after 9 to 11 months, from leaf look, this time by the pumping large leaves 1 to 2 to short round spade leaf , leaves began to turn away from the most sparse dense foliage pumping speed slowed ; see from the stem , pseudostem development to the most coarse , corms ( banana head ) begins on the exposed surface , weed killer sprayer was the altar -shaped ; see from suckers have entered suckers Sheng period . This period is in the reproductive growth bud differentiation process that requires a lot of nutrients for growth and development of young spike , spike big fruit in order to form long ear . According to overseas research , when the late vegetative stage into the flower bud , leaf nitrogen content plummeted , because then need to use a lot of nitrogen supply bud , when the roots absorb nitrogen from the soil can not meet the need , nitrogen had from the leaves , stems and other tissues and organs transferred over. Then re-applied fertilizer , can promote the blade for maximum assimilation , creating more organic matter for the panicle formation and growth and development.
