Abstract
Rapeseed Planting as Green Manure Improving Rice Growth and Production
Highlights
The effect of applying chemical fertilizers on field ecosystems, such as soil structure destroying, fertility dropping, etc, is becoming a matter of concern in China with the extensive application of fertilizers
The results showed that the rice plant height and chlorophyll content increased under the treatment of rapeseed returning as green fertilizer, and increased under 20% fertilizer reduction after rapeseed returning to field
The result illustrated that rapeseed planting as green manure can improve plant height of rice, and there was no obviously effect on plant height under 20% fertilizer reduction after rapeseed returning to field
Summary
The effect of applying chemical fertilizers on field ecosystems, such as soil structure destroying, fertility dropping, etc, is becoming a matter of concern in China with the extensive application of fertilizers. The glucosinolates in rapeseed were expected to be effective in suppressing harmful bacteria, spines and weeds growth, which had definite effect in overcoming the continuous cropping obstacle and increasing the resistance, yield and quality of rice (Handisenia et al, 2013; Gu et al, 2019). It is of great significance for building ecological agriculture system and raising yield when developing rapeseed planting to reduce winter bare fields. The test of green manure returning to field with fertilizer application reducing was carried out to clear the amount of rapeseed returned to provide the interest information for rapeseed planting as green manure
