蔗地采用立体栽培组合新技术，前期亩均增收200－300元，中后期亩均增收1000－1500元，甘蔗增产13％一16％，糖甜度可提高了0．28－0．62个百分点，还能改善土壤结构，培肥地力。一、蔗地前期。在蔗行间种的作物应是生育期短，株型矮小，早熟、高产、管理方便，能在甘蔗苗封行?
Cultivated land uses three-dimensional cultivation of new technologies, pre-average income 200-300 yuan per mu, mid-late acres average income 1000-1500 yuan, sugar cane yield 13% to 16%, sugar sweetness can be increased by 0.28-0.62 Percentage points, but also improve the soil structure, fertility fertility. First, sugarcane early. Crops between rows of cane lines should be short growth period, short plant type, early maturity, high yield, easy management, in sugarcane seedling envelope?
