挖沟留土植蕉是解决坡地蕉园培土和提高保水能力的重要措施.以往坡地采用台面挖小穴种蕉,由于土源不足,无法实现年年培土作业,且小穴无保、蓄水的作用,致使蕉头和根系外露,根系难以生长,影响养分和水分的吸收,减缓了香蕉的生长和发育,使产量和质量下降,加重病害和风害,缩短蕉园寿命.1987年我们采用挖沟留土植蕉后,经5年来的观察,证明此法可实现年年培土作业;可减轻风害5.86%;减轻束顶病8.42%;提高抗旱能力.已在部分植蕉区推广.
Digging the ditch to keep soil planting banana is an important measure to solve the problem of cultivating soil and improving the water holding capacity of the banana plantation in the past.During the past, the use of mesa digging small hole species banana, because of insufficient soil, can not achieve annual earthwork, , Resulting in banana head and root exposed, difficult to grow the root system, affecting nutrient and water absorption, slowing the growth and development of bananas, so that the yield and quality decline, increasing disease and wind damage and shorten the life of banana.In 1987 we use digging ditch stay Soil plantation banana, after 5 years of observation, this method can prove that this method can achieve earthwork every year; can reduce wind damage 5.86%; alleviate beam top disease 8.42%; improve drought resistance.
