目前,番石榴主要是用传统方式栽培,由于植株高大,单位面积产量低,需劳力较多,加上非生产期有几年,因而成本较高。为此,急需改良传统的栽培方法。几种现代水果生产制度业已应用于温带水果生产。草场式果园,即高度集约的经营针度是一种最有效的现代果树生产制度,其突出的优点是节省劳力。这种制度应用化学处理,使两年生的果树产果,收割机象割草一般连树带果全部收获。 At present, guava is mainly cultivated in the traditional way, because of its tall plants, low yield per unit area, more labor required, and the non-production period of several years, resulting in higher costs. Therefore, there is an urgent need to improve the traditional cultivation methods. Several modern fruit production systems have been used for temperate fruit production. Grassland-type orchards, that is highly intensive management of acupuncture is one of the most effective modern fruit tree production system, which has the outstanding advantage of saving labor. This system uses chemical treatment, so that two biennial fruit trees, harvesters, mow trees and fruit trees are generally harvested.
