CHINA: An Opportunity for Regenerative Rice Production: Combining Plastic Film Cover and Plant Biomass Mulch with No-Till Soil Management

CHINA: An Opportunity for Regenerative Rice Production: Combining Plastic Film Cover and Plant Biomass Mulch with No-Till Soil Management | SRI Global News: Nov. 2023 - Jan. 2024 **sririce.org -- System of Rice Intensification | Scoop.it

China has attained rice sufficiency with the increased use of nitrogen (N) fertilizer, but this has led to serious N pollution. Using plastic film on raised-beds, combined with improved agronomic practices, can boost rice yield by 50% with 36% less N fertilizer use, 30% higher NUE, and stabilized the yield of 9.75 t ha−1. It also counters the effects of drought and low ambient temperature. A six-year study was conducted combining no-tillage, crop-residue mulch, and plastic cover, alternating organic rice and rapeseed production. The plastic cover integrated technology (PCIT) reported on here combines the use of plastic film to cover the raised beds with improved agronomic practices from the System of Rice Intensification (SRI). All the treatments, fertilized with biogas slurry and rapeseed meal, gave rice yields of 7.0 to 10.7 t ha−1, well above China’s average of 6.5 t ha−1. In this time, soil organic matter increased from 1.6% to 4.2%. In the first four years, the combination of crop-residue mulch with plastic cover had a slightly higher yield than mulch alone. In the fifth and sixth years, the latter treatment surpassed the use of plastic cover with crop-residue mulch. Trials with a biodegradable film show that plastic pollution can be dealt with.

KENYA / CHINA: Improving Productivity of Rice under Water Scarcity in Africa: The Case for SRI

 Bancy Mati, Professor at Jomo Kenyatta University of Agriculture and Technology, presented a talk on "Improving Productivity of Rice under Water Scarcity in Africa: The Case for the System of Rice Intensification" on June 26, 2019, at the International Rice Development Conference and Seminar on China-Africa Development, in Changsha, China

CHINA: 用自然农法从事农业生产能赚钱吗?


工业化食物系统现在无法养活世界(目前有10亿人口营养不良),
而用农业生态的办法可能可以养活几倍于目前全球数量的人口,
同时也能恢复自然系统的健康状态。
一个例证是水稻强化栽培体系
(System of Rice Intensification),也称作SRI,是一种通过改变作物、土壤、
水体和营养成分的管理办法以增加灌溉水稻产量的农业生态方法。
20世纪80 年代,SRI起源于马达 加斯加,是基于使用更少和更小的种苗、
自然施肥以及减少用水量等耕种原则。
[...The industrial food system currently in use doesn't feed the whole world, (1 billion undernourished), while agro-ecology could potentially feed the world several times over while restoring health to natural systems.  One example: the System of Rice Intensification, known as SRI, is an agro-ecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients....]
