近年来,不少果园种植番木瓜时都发生果实瘤状病.患有该病的植株,其果实的表面有许多不规则的瘤状物凸起.掌状叶的尖端逐渐向内变褐枯萎,严重时花蕾干枯脱落,茎尖生长停顿,节间缩短,甚至秃顶.病果凹凸不平,伤疤较多,一般每个果有瘤5～8个,多者近20个,病部占果面有的达80%以上.这种果实在接近成熟时,病疤地方常先发软,继而霉菌侵入,于是出现炭疽病并烂果现象.即使不发生烂果,那副“尊容”摆在柜台上,也会使顾客望而生畏;如采青果做为蜜饯原料,因需切削过多,造成不必要的浪费.大大降低了商品价值,给种植者带来一定的经济损失.
In recent years, many fruit orchids occur when growing papaya in the orchards, and the plants suffering from the disease have many irregular knobs protruding from the surface of the fruit. , Serious dry buds fall off, the growth of the shoot tip pause, internodes shortening, or even bald. Diseases uneven, more scars, generally each tumor has 5 to 8, more than 20, the disease accounted for the fruit surface And some reached more than 80% .This fruit is near maturity, the scar area often first soft, then mold invade, so there anthrax and rotten fruit phenomenon.Although no rotten fruit, the pair of “respect” placed On the counter, it will also make customers daunting; such as mining fruit as candied fruit raw materials, due to the need to cut too much, resulting in unnecessary waste, greatly reducing the value of the goods, to growers to bring some economic losses.
