Effects of Application of Controlled Release Nitrogen Fertilizer on N_2O Emission in Slope Cultivated Land with Purple Soil
2017年
In order to study effects of application of contmllE=d release fertilizer on ni- trous oxide (N2O) emission in slope cultivated land with purple soil, four treatments including the control group (CK), urea (UR), controlled release nitrogen fertilizer (CR), and controlled release nitrogen fertilizer+urea (25%CR, 75%UR) were set up, and their impacts on maize yield, surface runoff and nitrogen loss in the growth pe- riod of maize and N2O emission were studied. The results show that maize yield, surface runoff, nitrogen loss from subsurface flow, and N2O emission in the control group was far lower than that in the fertilization treatments, revealing that fertilization was the main reason for nitrogen loss and N2O emission. Among the four treat- ments, nitrogen loss from subsurface flow in the treatment CR was the highest, up to 31.7 kg/hm^2, but N2O emission was 0.35 kg/hm^2, which was 37% less than that in the treatment UR. Nitrogen loss from subsurface flow in the treatment 25% CR was the lowest, only 20.9 kg/hm^2, and N2O emission was 15% less than that in the treatment UR. Nitrogen was slowly released from controlled release nitrogen fertilizer in the growth period, and controlled release nitrogen fertilizer could reduce N2O emis- .sion from slope cultivated land due to low content of soil inorganic nitrogen, but it could increase the nitrogen loss from subsurface flow. Therefore, the combination of controlled release fertilizer and urea can not only reduce N2O emission but also de- crease nitrogen loss from subsurface flow.

四川省农作物种植结构与气候变化耦合协调性研究被引量:2
2022年
为了探究四川省作物种植结构与气候变化的协调关系,本研究基于四川省气候数据与农作物播种面积数据,分析了2000—2018年四川气候变化、农作物种植结构变化以及它们之间的协调关系。结果发现:四川省2000—2018年间降水量、≥10℃积温均呈显著上升趋势,降水量气候倾向率为53.5 mm/10 a,≥10℃积温气候倾向率为123.7℃/10 a;作物播种面积明显增加的有玉米、油料作物、豆类、果园,薯类播种面积保持相对稳定状态,作物播种面积明显下降的有水稻、小麦和其他作物;各主要农作物种植结构占比变化明显。四川省农作物种植占比前三种为水稻、玉米和薯类,多年平均占比分别为21%、17%和13%,且水稻在所有种类中占比较稳定;小麦种植占比正在逐年降低。四川省2000—2018年农作物种植结构变化与气候变化整体相互适应,耦合度与耦合协调度均较高。

生物动力农业
2008年
什么是生物动力农业?为寻求这个答案,我们先提出这样的问题:地球能自我伤愈吗?地球是否会因自身的活力过分衰减而无法自我伤愈?无论我们身处何地,只要注意观察,就会发现树木、作物、水,甚至气候明显的病症。

Effects of Nitrogen,Phosphorus and Potassium Application on Growth and Dry Matter Accumulation in Mulberry被引量:1
2013年
In this paper, the effect of different fertilizer treatments on the main indexes of growth and development and dry matter accumulation of perennial mulberry, which is cut and pruned in summer, were studied with ‘3414’ field experiment design. The results showed that N, P, and K at proper amounts could promote mulberry growth and development, improve its dry matter content, increase its dry matter accumulation. The effects of N, P, K on leaf yield per plant were respectively expressed as follows: N2 N3 N1 N0 , P2 P1 P3 P0 , K2 K1 K3 K0 . It can be concluded that the recommended fertilizer amounts of dry matter accumulations in mulberry leaf were 694.36 kg/hm2 of N, 198.15 kg/hm2 of P, and 274.26 kg/hm2 of K and the dry matter achieved the maximum at 8 045.04 kg/hm2 . The recommended fertilizer amounts of accumulated dry matter in branch were 1 000.05 kg/hm2 of N, 242.04 kg/hm2 of P, and 218.01 kg/hm 2 of K, and the dry matter achieved the maximum at 5 969.05 kg/hm2 . The recommended fertilizer amount in young shoots were 883.76 kg/hm2 of N, 204.48 kg/hm2 of P and 426.59 kg/hm2 of K and dry matter achieved the maximum at 1 410.24 kg/hm2 . This paper could provide reference for the construction of highly-qualified mulberry field in Sichuan hilly area.

浅议蚕桑文化产品的价值构成及市场走向被引量:3
2021年
我国种桑养蚕缫丝织绸的历史已有5000多年,蚕桑文化成为一种精神现象,其影响源远流长。蚕桑文化产品则是以蚕桑文化为基础建立的综合产业,具有鲜明的中国特色。本文在概述蚕桑文化的意识形态载体和非意识形态载体的基础上,提出当代蚕桑文化产品的市场将向着高质量、绿色低碳、多元化、现代化和国际化方向发展,并指出四川省当前蚕桑文化产品产业发展应以实现超大集群的产业规模、培育壮大具有文化属性的新型生产经营主体为基础。

从土壤保持角度探索全国生态桑产业发展布局
2024年
桑树具有十分强大的土壤保护功能。本文基于全国生态功能区划,瞄准生态桑在土壤保持生态系统服务功能中持续作用的重大科学问题,考量了桑树在各类生态重点区域的定位和价值实现途径。通过分析各生态区域蚕桑产业发展的基础状况,确定了西南喀斯特区、川滇干热河谷区、三峡库区、黄土高原区、鲁中山区和昆仑山区等6个桑树土壤保持核心服务区。针对上述6个桑树土壤保持核心服务区的产业生态特征,分别提出了保墒增碳、护土保水、保土降污、屯水治沙、肥土增碳和防风固沙的土壤管理技术,并推荐了广西宜州、四川盐边、重庆巫溪、陕西榆林、山东烟台和新疆和田等6个技术先行示范区。

Effects of Different Tillage and Mulching Modes on Tobacco Output Value and Soil Quality
2014年
Based on three years of long-term fixed-site field trial, the effects of differ- ent tillage and mulching modes on the yield and output value of tobacco and soil quality were investigated. The results showed that the yield and output value of to- bacco in tillage treatment were improved by 22.72 % and 37.23 % compared with non-tillage treatment, respectively; the yield and output value of tobacco in rotation treatment were improved by 1.83% and 19.41% compared with continuous cropping treatment, respectively; the yield and output value of tobacco in straw mulching treatment were improved by 3.55% and 2.4% compared with non-straw mulching treatment, respectively, which indicated that tillage, rotation and straw mulching could improve the yield and output value of tobacco to a certain extent; especially, the yield and output value of tobacco increased significantly after plowing under rotation conditions. The contents of available phosphorus (AP), alkali-hydrolyzable nitrogen (AN), organic matter (OM), total nitrogen (TN) and total phosphorus (TP) in non- tillage treatment were 35.14%, 9.92%, 9.57%, 4.40% and 34.16% higher compared with tillage treatment; especially, under non-tillage conditions, soil pH and contents of available potassium (AK), AP, AN,OM,TN,TP and total potassium (TK) in continu- ous cropping field were 2.01%, 48.68%, 73.09%, 11.45%, 7.71%, 7.31%, 47.68% and 11.78% higher compared with rotation field, indicating that non-tillage treatment and continuous cropping could improve the total content and available content of organic matter, nitrogen and phosphorus. Therefore, from the perspective of soil fer- tility improvement and sustainable tobacco production, continuous cropping under non-tillage conditions might be the most appropriate cropping pattern for local soil fertility improvement; aiming at improving the yield and output value of tobacco, green manure-tobacco→, green manure/wheat/maize→green manure-tobacco ro- tation might be the most appropriate cropping pat

种养分离对蚕桑产业绿色发展的潜在意义探析
2023年
面对全产业链发展与绿色发展的耦合协调需求,模块化生产和产品内分工是现代产业发展的主流趋势。以蚕茧生产中栽桑环节和养蚕环节的分工为题,讨论分析了种养一体的局限性和种养分离的优势,探讨了种养分离下的收益分配方式,提出当前桑叶的最低收购价保持在1.5元/kg才有利于维持桑叶生产的平稳健康发展。期望通过揭示种养分离的高效、可持续性,推动蚕桑产业绿色低碳发展。

桑树新生枝条和叶片中的养分分配格局研究被引量:3
2017年
养分的组成和含量是评价桑叶对蚕的营养价值的主要依据。采用雾化栽培技术开展试验,测定分析桑树新生枝条和叶片的干物质含量以及全氮、全磷、全钾、总钙和总镁含量的空间分配格局,探究养分分配与桑枝粗细的关系。桑枝粗细与叶片主要养分的含量呈显著相关,枝条越粗,桑叶中的全氮、全磷、总钙和总镁的含量也越高;从枝条的基部到顶部,桑叶中的干物质含量以及总钙、总镁含量表现出逐渐降低的趋势,全氮和全磷含量则表现出显著增加的趋势,而全钾的含量变化不显著。桑枝粗细与枝条中的干物质含量以及全钾和总镁含量呈显著相关,而与全氮、全磷和总钙的含量无显著相关性;枝条从基部到顶部,枝条中的干物质含量呈现逐渐降低的趋势,而全氮、全磷、全钾、总镁和总钙含量则表现出逐渐增加的趋势;随着桑枝的增粗,枝条中部的干物质含量减少的程度显著高于基部和顶部,枝条顶部的全钾和总镁含量减少的程度显著高于基部和中部。上述研究结果提示桑园施肥应注意钾肥和镁肥的合理搭配,桑叶采摘后应注意追施氮肥、磷肥和钙肥。
