| Hay is one of the main feed of the herbivore livestock on raise time,sothe preparation and storage of a large number of high quality hay, is the important guarantee for the herbivore livestock in the season subtilis of winter and spring.Based on the analysis on water loss,the main of nutritional value indicators, leaf loss rate and microstructure of alfalfa hay under the physical treatment and chemical treatment, in order to screen out the most optimal modulation technology, to provide technical support and theoretical basis for livestock development and production activities of farmers and herdsmen in Inner Mongolia. The results showed:(1)Comparing to the physical treatments,the concrete floor+(cut+squash) treatment has the fastest water loss processing of alfalfa hay,the least leaf loss,maintains the best nutrition,is the best way on the single physical treatment.And the modulation floor for alfalfa hay is the concrete floor more effective than the field.(2)Comparing to the chemical treatments,the treatment to spray 2%K2CO3 solution treatment has the fastest water loss of alfalfa hay, the least leaf loss,maintains the best nutrition,is the best way on the single chemical treatment.(3)Under the physical treatment and chemical treatment working together,the cut+squash +2%K2CO3 solution treatment has the fastest water loss of alfalfa hay,maintains the best nutrition.(4)By using different drying methods to modulate the alfalfa hay, from the microscopic structure of alfalfa stem and leaf,to compared to explain the most optimal conditions is: comparing with other treatments,the cut+squash+2%K2CO3 solution treatment can significantly speed up the drying speed of alfalfa,minimize the loss of alfalfa leaves, preserve nutritional content of alfalfa hay. |
