Effect of Fertigation on Macadamia integrifolia Production |
| |
| Abstract: | Objective] The objective was to explore the effects of fertigation on Macadamia integrifolia production, sum up a suitable fertiga-tion technology for Macadamia integrifolia.. Method] Set six different treatments:annular drip irrigation high quality fertilizer,annular drip or-ganic fertilizer, annular drip common fertilizer, fixed-point drip common fertilizer, sprinkling irrigation common fertilizer and conventional fer-tilization .Effect of different treatments on yield ,fruit drop and size was researched. Result] Among six treatments, annular drip organic fer-tilizer was the best , which yield was 5969.7 kg/hm2 ,increased by 15.96%, fruit drop was decreased by 24.11%.The economic benefit reached 9.55 ×104 yuan/hm2 and the cost was 1.26 ×104 yuan/hm2 .In contrast to the conventional fertilization, profits increased by 17800 yuan /hm2.Conclusion] Fertigation technology-ring drip organic fertilizer for Macadamia integrifolia can effectively improve the yield and fruit size, reduce the fruit drop rate and increase production and economic benefit. |
