Transcript

  • 1. Achievements/outputsagainst objectives and activities 1
  • 2. Objective 1: Develop and test appropriate machinery designed around 20hp tractors to mechanise PRB in wheat/maize systems1.1. Survey current farm machinery available in north western China Achievements A mechanisation survey was conducted at the beginning of the project 2
  • 3. 1.2. Develop and test bed forming and furrow forming machinery Achievements A tested and operational bed former has been developed and is ready for commercialisation. A machinery company (Zhulong Factory) has been identified. 3
  • 4. 1.3. Develop and test commercial zero till wheat/maize drills for PRB and bed harvesters AchievementsA passive anti-blocking no-till planter (2BFML-5 no-till planter) for <3.7t/ha residue cover fields wasdeveloped with moderate success and will be readyfor commercialization after minor modifications.A strip-chopping no-till planter (<350kg loaded) for allkinds of residue cover conditions was developed withmoderate success, and will be commercialized afterultra narrow tines and adjustable flails are fitted.A power driven disc planter was tested and will beused as an alternative planter option to plant in heavyresidue cover fields after moderate modification. 4
  • 5. The data on effectiveness of no-till planter and harvester are available. A machinery company (Wangnongda Factory) has been identified. 5
  • 6. A 20hp tractor-mounted harvester prototype for current PRB system in Hexi Corridorhas been developed based on some current existing work components, and is readyfor commercialisation after wider front and lower centre of gravity is achieved. 6
  • 7. 1.4. Integrate mechanical weed control AchievementsA sprayer-cultivator-combined weeder was developed successfully and is ready forcommercialization based on two years’ testing and development. 7
  • 8. 1.5. Develop a simple, furrow-based tractor guidance system AchievementsA tractor guidance system using mechanical tactile sensors guided by maize stalkhas been developed successfully.A planter guidance system guided by furrow was tested and will be used as analternative guiding option to achieve long term precision of bed position aftermoderate modification to suit various tractor configurations. 8
  • 9. Objective 2: To compare crop performance, residue and water management of current practices, modified current practices and permanent raised beds in wheat /maize systems of the Hexi Corridor 9
  • 10. 2.1. Compare water productivity & monitor water and salt balances Achievements Comprehensive soil water, salt and irrigation water savings data sets have been compiled and analysed from 2006-2009. FRB PRB CT ZT 750 During production irrigation water (mm) cycle of spring 650 wheat, compared 550 with CT , 450 PRB saved 350 irrigation water 21.21% ~ 42.54% 250 2006 2007 2009 years Irrigation water for different cultivation methods during production cycle of wheat 10
  • 11. 650During maize growth period, the irrigation water(mm) 550irrigation water for PRB is the least at 450456.6mm,compared with CT. Savedirrigation water 27.7% at 174.97mm. 350 250 FRB PRB CT ZT treatments 11
  • 12. 12
  • 13. 2.2. Assess crop performance and soil responses (PC) AchievementsComprehensive crop performance data sets have been compiled and analysed forfour seasons from 2006 to 2009.Low soil temperature caused by stubble covering mainly, slowed maize maturityand resulted in significant yield penalties.Comprehensive soil chemical sampling and analysis has been carried out,indicating the NUE for PRB is higher than other treatments 13
  • 14. 2.3. Crop residue management (PC) AchievementsSoil biological analyses indicate a shift in microbial populations, reflecting a slightlymore beneficial (aerobic) soil environment under PRB; this may be related to theobserved lower incidence of soil borne diseases common in conventional tillage.Compromise stubble retention rates of standing wheat stubble of 20 cm height andmaize stubble of 10cm that effectively reduce wind erosion, yet do not overly retardsoil warming in spring have been identified. 14
  • 15. 2.4. Train Chinese scientists in on-farm experimental methodology (A) Achievements Two Chinese delegations have been exposed to and trained in some of the experimental techniques required in the field work, as well as being exposed to Australian agriculture, machinery manufacturers and other research organisations working on PRB in Australia. The Chinese scientists in the project have been trained for CA technique and machinery in Beijing. Five stages of farmer field school have been organized in Ganzhou District, Minqin county, Suzhou District, Liangzhou District, Shandan County. 15
  • 16. Objective 3: To assess the cost benefit of PRB farming systems 16
  • 17. 3.1. Design and conduct baseline socio-economic survey (PC) Achievements Village Shilipu Farmers (# surveyed) 15 Land area (ha) 1.2 number of blocks in land area 6.3 Age (yrs) 49 Education (level) 6 Household (persons) 3.9 Labour (persons) 1.8 Av Household annual income (Yuan) 13260 Av gross income (Yuan/ha) 10000 Av farm gate price (Yuan/kg) 1.52 Herbicide (Yuan/ha) 73 Diesel Fuel (Yuan/ha) 464 Water pumping (Yuan/ha) 417 Labour (Yuan @ 70mandays/ha) 1400 Contract Ploughing (Yuan/ha) 240 Contract Harvest (Yuan/ha) 375 Family Labour (Yuan @ 70mandays/ha) [not costed] 1400 Fertiliser (manure and manufactured) (Yuan/ha) 2480 Seed (Yuan/ha) 754 Total inputs (Yuan/ha) 6203 17
  • 18. 3.2. Conduct cost benefit analysis of new PRB system (PC) AchievementsFinal CB Survey conducted in Suzhou, Shandan, Liangzhou and Zhangye during September 2009 Report and complete data set not available 18
  • 19. Objective 4: Extend PRB technology 19
  • 20. 4.1. Expose Chinese extensionists to Australian extension programs (A) Achievements Two delegations of extensionists have been exposed to Australian agriculture, machinery manufacturers and other research organisations working on PRB in Australia. 2,000 Chinese farmers and 160 extensionists have been trained. 10,000 farmers have received information on PRB and CA technique. 20
  • 21. 4.2. Establish on-farm PRB demonstration sites (PC) AchievementsThree demonstration sites have been set up in Shandan County, Suzhou Districtand Liangzhou District. Suzhou demonstration site Liangzhou demonstration site Shandan demonstration site 21
  • 22. 4.3. Extend PRB beyond Zhangye county (PC) AchievementsBed planting and furrow irrigation technique has been applied to 20,000ha inHexi Corridor. 22
