Comprehensive Evaluation of Integration Modes of Agricultural Machinery and Agronomy for Baby Cabbage Based on Principal Component Analysis
In order to find the optimal integration mode of agricultural machinery and agronomy for transplanting baby cabbage on film,and provide references for the promotion of mechanized transplanting and transplanting machine for baby cabbage,two kinds of integration modes of agricultural machinery and agronomy including double-row mechanical transplanting and three-row mechanical transplanting were set up with three kinds of plant-row spacing,respectively,which were 15 cm × 40 cm,20 cm × 40 cm,25 cm × 40 cm for double-row mechanical transplanting and 20 cm × 25 cm,25 cm × 25 cm,30 cm × 25 cm for three-row mechanical transplanting,by taking best-selling baby cabbage variety'Yinong Huangfei F1'as the test material and manual transplanting as the control,respectively.From 15 indexes such as agronomic characters,yield,transplanting efficiency and economic benefit of baby cabbage and so on,different integration modes of agricultural machinery and agronomy were comprehensively evaluated and analyzed.The results showed that the treatment of double-row artificial transplanting(with plant-row spacing of 15 cm × 40 cm,planting density of 133 400 plants/hm2)had the highest comprehensive evaluation F value of 2.184,with the highest comprehensive benefit of 38 654.44 yuan/hm2.Followed by the treatment of double-row mechanical transplanting(with plant-row spacing 15 cm × 40 cm,planting density of 133 400 plants/hm2),with the F value of 1.548,and the comprehensive benefit was 34 613.14 yuan/hm2.The treatment of three-row artificial transplanting(with plant-row spacing 25 cm×25 cm,planting density of 100 050 plants/hm2)had F value of 1.194,and comprehensive benefits of 35 697.54 yuan/hm2.When mechanical transplanting is being adopted in baby cabbage cultivation,it is more suitable for planting mode of double-row per ridge.The effect of integration of agricultural machinery and agronomy was the best with the plants row spacing of 15 cm×40 cm and the planting density of 133 400 plants/hm2 in mechanical transplanting,which transplanting time,yield,gross economic output value and net economic income of 128.44 h/hm2,111 846.9 kg/hm2,67 108.14 yuan/hm2 and 34 613.14 yuan/hm2,respectively.
