Abstract:
To investigate the effects of different organic fertilizers, sowing rates, and harvesting times on the growth and yield of
Brassica rapa, Jinpin No. 5
Brassica rapa was selected as the test variety. A single factor experiment was conducted, with five types of fertilizers(Haizhuangyuan Biological Organic Fertilizer, Yali Yali Biological Organic Fertilizer, Gepin Biological Organic Fertilizer, Granular Sheep Manure, and Fermented Chicken Manure), three sowing rates(4.0, 8.0, and 12.0 g), and three harvesting times(23rd, 25th, and 27th days after sowing). Based on the single factor experiment, an L9(3
3)orthogonal experiment was further conducted. The results showed that in the single factor experiment, the treatments with the highest yield in the
Brassica rapa plot were the application of organic fertilizer with Yali Yali Biological Organic Fertilizer, a sowing amount of 12 g, and a harvesting time of 27 days after sowing. In the orthogonal experiment, the degree of influence of the three factors was as follows: harvesting time>sowing amount>fertilizer type. Under the conditions of using Yali Yali Biological Organic Fertilizer sowing amount of 12.0 g, and harvesting time on the 27th day after sowing, the yield of
Brassica rapa was the highest, equivalent to
28352.9 kg·hm
−2, and the commercial value was good.
