生物菌肥对饲用马铃薯营养品质、产量构成与碳氮代谢酶的影响
Effects of biofertilizer on the nutritional quality,yield composition,and carbon and nitrogen-metabolism enzymes of feed potatoes
摘要
Abstract
The experiment used the feed potato"Yushangshu No.12"as the test material,and with the help of a completely randomized block design,explored the effects of different levels of biofertilizers(0 kg/hm2,675 kg/hm2,1350 kg/hm2,2700 kg/hm2,5400 kg/hm2)on the nutritional quality,yield composition,and carbon and nitrogen metabolism enzyme activity of feed potatoes,in order to provide theoretical basis for the efficient utilization of feed potatoes in animal husbandry production.The results showed that biofertilizer could improve the nutritional quality of feed potatoes.Quality indicators such as protein,starch,reducing sugar,and vitamin C content showed a single peak trend of first increasing and then decreasing with the increase of biofertilizer dosage.The values of the above indicators were the highest when the biofertilizer dosage was 2700 kg/hm2(BM3),which increased by 17.19%,20.90%,27.62%,and 11.77%respectively compared with the control CK,and the difference between the two groups was significant(P<0.05).The appropriate amount of biofertilizer can significantly increase the number of tubers per plant,the quality and yield of potato tubers per plant,and improve the proportion of marketable tubers.The best effect is achieved with the use of biofertilizer under BM3 treatment.There are differences in the effects of different levels of biofertilizers on the activity of carbon and nitrogen metabolism enzymes in feed potatoes.However,when the dosage is 2700 kg/hm2,the activities of sucrose synthase,sucrose phosphate synthase,nitrate reductase,and glutamate synthase are relatively high,increasing by 25.72%,18.43%,and 31.05%,25.23%,respectively,compared with the control,and the difference is significant(P<0.05).There is a highly significant(P<0.01)positive correlation between sucrose synthase,sucrose phosphate synthase,nitrate reductase,and glutamate synthase and the quality and yield of feed potatoes per plant.关键词
