一、概况早已认识到钾是椰子最广泛需要的元素,但给椰子施的钾肥仍然不多。传统的高种椰子是迟熟种,它对环境改良的反应也是迟缓的。一般在大田定植后6—9年才开始结果,12—15年进入丰产期。而现代杂交种第4年就开始结果,第7年即进入丰产期。而且,它们比未经改良的高种椰子多产椰果2—3倍。在不久的将来,椰干的产量将达到每公顷10吨以上。显而易见,这样的高产植株其所需的养分将是
First, the profile has long recognized that potassium is the most widely needed element of coconut, but the application of potassium to coconut is still modest. The traditional high-coconut is a late-maturing species whose response to environmental improvement is also sluggish. Generally 6 to 9 years after colonization in Daejeon began the results, 12-15 years into the high yield. The first 4 years of modern hybrids began the results, the first 7 years into the high yield. And, they are 2-3 times more productive than unmodified high-coconut. In the near future, copra production will reach more than 10 tons per hectare. Obviously, such high-yielding plants will have the nutrients they need
