Journal ArticleDOI
Estimates of rice lodging using indices derived from UAV visible and thermal infrared images
Tao Liu,Rui Li,Xiaochun Zhong,Min Jiang,Xiuliang Jin,Ping Zhou,Shengping Liu,Chengming Sun,Wenshan Guo +8 more
TL;DR: In this paper, the authors collected visible and thermal infrared images with an unmanned aerial vehicle and established a comprehensive rice lodging recognition model using a particle swarm optimization and support vector machine algorithm.
Journal ArticleDOI
Effects of high temperature after anthesis on starch granules in grains of wheat (Triticum aestivum L.).
TL;DR: The results showed that the starch concentration of grains given a heat-shock treatment above 30°C were lower than those developing at normal temperature in both cultivars, indicating the differences in resistance to high temperature between cultivars.
Journal ArticleDOI
A quantitative approach to characterize sink―source relationships during grain filling in contrasting wheat genotypes
TL;DR: In this article, the authors present a generic framework to quantify source-sink relationships during grain filling, by using a determinate growth function which has a unique property, namely being able of explicitly describing the time for the end of a growth process.
Journal ArticleDOI
Assessment of the AquaCrop model for use in simulation of irrigated winter wheat canopy cover, biomass, and grain yield in the North China Plain.
Xiuliang Jin,Hai Kuan Feng,Xin Kai Zhu,Zhenhai Li,Sen Nan Song,Xiao Yu Song,Guijun Yang,Xin Gang Xu,Wenshan Guo +8 more
TL;DR: It is concluded that AquaCrop is a useful decision-making tool for use in efforts to optimize wheat winter planting dates, and irrigation strategies, and that frequent irrigation with a small amount of water significantly improved BY and GY.
Journal ArticleDOI
Effect of nitrogen levels and nitrogen ratios on lodging resistance and yield potential of winter wheat (Triticum aestivum L.).
Mingwei Zhang,Hui Wang,Yuan Yi,Jinfeng Ding,Min Zhu,Chunyan Li,Wenshan Guo,Chao-Nian Feng,Xinkai Zhu +8 more
TL;DR: A field experiment with Yangmai 20 was conducted to study the effects of different nitrogen levels and ratios on culm morphological, anatomical characters and chemical components and to explore the nitrogen application techniques for lodging tolerance and high yield, suggesting a combination of planting density and nitrogen level and ratio could effectively relieve the contradiction between high-yielding and anti-lodging.
