ABSTRACT

This study evaluated the productivity and nutrient concentrations of organic cherry tomatoes and leguminous green manures grown in intercropping systems in rotation with maize. The experimental design was a complete randomised block design with five replications and eight treatments, as follows: monocrop of cherry tomato adding residual maize crop residue (straw) as a mulch (control), monocrop of cherry tomato without the addition of maize crop residue (control), cherry tomatoes intercropped with jack bean, sun hemp, dwarf velvet bean, mung bean, white lupin or cowpea bean grown as green manures. In this production system, which was evaluated between 2011 and 2013, maize was cultivated from January to April, and the cherry tomatoes, with or without leguminous green manures, were grown from May/July to November/December. The number and weight of total and marketable fruits of tomatoes were 70% – 88% higher in 2011 than in 2012 and the number of damaged fruits was 12% lower in 2011 than in 2012. In 2011, the weights of total and marketable fruits in the intercropping treatment with white lupin were lower than that in the controls and in the intercropping treatments with dwarf velvet and cowpea bean. The white lupin and sun hemp green manures produced the highest biomass dry weight, followed by the jack bean, cowpea bean, mung bean and dwarf velvet bean. The different treatments had no effect on the yield of the maize.

摘要

本研究评估了在与玉米轮作系统中种植的有机樱桃番茄和豆科绿肥的生产力和养分浓度。试验设计为完全随机区组设计，5个重复，8个处理，如下：樱桃番茄单一作物添加玉米秸秆（秸秆）作为覆盖物（对照），樱桃番茄单一作物不添加玉米作物秸秆（对照），樱桃番茄与长豆、太阳大麻、矮绒豆、绿豆、白羽扇豆或作为绿肥种植的豇豆间作。在 2011 年至 2013 年评估的这个生产系统中，玉米在 1 月至 4 月期间种植，樱桃番茄在 5 月/7 月至 11 月/12 月期间种植，无论是否施用豆科绿肥。2011 年番茄的总果实和可销售果实的数量和重量比 2012 年增加了 70% - 88%，2011 年受损果实的数量比 2012 年减少了 12%。 2011 年，番茄的总果实和可销售果实的重量白羽扇豆间作处理低于对照和矮绒、豇豆间作处理。白羽扇豆和太阳麻绿肥产生的生物量干重最高，其次是杰克豆、豇豆、绿豆和矮绒豆。不同处理对玉米产量无影响。间作白羽扇豆的果实总重和适销果重均低于对照及间作矮绒和豇豆。白羽扇豆和太阳麻绿肥产生的生物量干重最高，其次是杰克豆、豇豆、绿豆和矮绒豆。不同处理对玉米产量无影响。间作白羽扇豆的果实总重和适销果重均低于对照及间作矮绒和豇豆。白羽扇豆和太阳麻绿肥产生的生物量干重最高，其次是杰克豆、豇豆、绿豆和矮绒豆。不同处理对玉米产量无影响。
