Air method based on mountain green hay

Abstract

The invention discloses an airing method based on mountain green hay. The method comprises the following steps: manufacturing a grass airing frame; preparing airing of green hay; placing mown grass on the grass airing frame to air for 7-14 days; preparing the green hay. By adopting the method, season surplus-deficit can be adjusted, four-season balanced supply is ensured, regional surplus-deficit is adjusted, and development of the grass industry is prompted.

Description

technical field [0001] The invention belongs to the field of animal husbandry, and in particular relates to a drying method based on green hay in mountainous areas, especially suitable for drying green hay in mountainous areas with high humidity. Background technique [0002] Most of Bijie City in Guizhou Province belongs to the north subtropical monsoon climate with cool and humid climate and moderate water and heat resources. The annual average sunshine hours are 1101.8-1780.2 hours, the annual average temperature is 10-15.0°C, the average temperature in January is 17-4.3°C, the average temperature in July is 17.6-24.9°C, and the effective accumulated temperature of 10°C is 2544.6-4617.1°C; The average precipitation is 848.6-1394.4 mm, and the monthly variability is large. About 70% of the precipitation is concentrated in May to September; the frost-free period is 205-297 days, and the relative humidity is 60%-95%. Due to the special natural, economic and social conditi...

Problems solved by technology

Grass grows fast and yields high. The peak seasons of pasture grass production are mainly concentrated in March-June and September-November. The yield per mu can reach 500-1500 kg, and the yield of high-stem feed crops can even be as high as 10,000 kg. , the surplus of forage grass is particularly prominent. Due to the high rainfall and high air humidity in Bijie City, the traditional untimely use and the excess pasture grass being mowed and spread out in the field have led to the following bad results: First, the surplus The pasture grass is not mowed and grazing in the field, and the pasture grass naturally grows, heads, and ages to complete a growth period, which accelerates the degradation rate of the grassland and wastes forage resources.

The second is that the forage grass has not been scientifically processed, modulated and stored after mowing, and the forage grass rots seriously, which wastes both high-quality forage resources and human resources.

The third is that from April to November every year when the forage grows vigorously, the forage cannot be used up for a while, resulting in waste and degradation, and when the forage grows withered from December to March of the next year, there is no sufficient storage material, resulting in a shortage of forage

Silage is one of the important storage methods, which can better preserve the nutritional value and characteristics of forage grass. However, silage requires that the forage grass after cutting should be sealed and stored in time to avoid fermentation and rot. The processing time is short and the investment in infrastructure is large. Coupled with factors such as inconvenient transportation in mountainous areas and high labor intensity, the problem of forage storage cannot be completely solved.

Another way is to use coal or electric drying for storage, but at this stage, the cost of coal and electric drying is relatively high, and the labor intensity is also relatively high, which is not suitable for the development of animal husbandry in rural areas in mountainous areas.
