specific Embodiment approach 1

[0014] Specific embodiment one: the method for controlling locusts and raising poultry of a kind of northwest alpine grassland of the present embodiment is carried out according to the following steps:

[0015] 1. In late June every year, in winter and spring grazing pastures where locusts frequently occur and are seriously harmful, 25 to 30-day-old chicks of the green-footed hemp meat variety are introduced into winter and spring pastures for grazing; wherein, the juvenile and adult locusts in the pasture are mixed The population density is 10 heads / m 2 Above, the grazing intensity of the grazing chickens is 15-20 grazing chickens per hectare of grassland, the locusts start to move at 6 o'clock in the morning, go out for grazing when they jump, and return to grazing after the sun sets at 7 o'clock in the evening;

[0016] 2. Supplement high-energy feed corn every evening before the pastoral chickens return to pasture. The daily feed supplement amount of each chicken is propor...

specific Embodiment approach 2

[0023] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the weight of the chicks in step 1 is 600-700 g per chick. Other steps and parameters are the same as those in Embodiment 1.

[0024] Verify beneficial effect of the present invention by following test:

[0025] One, on June 22, 2007, in winter and spring grazing pastures where locusts frequently occur and are seriously harmful, 27-day-old chicks of the green-footed hemp meat variety were introduced into pastures for grazing; wherein, the mixed population density of locust larvae in the pasture The average is 13 heads / m 2 , the grazing intensity of the grazing chickens is 15 grazing chickens / ha grassland, and the grazing time is that locusts start to move at 6 o'clock in the morning and go out for grazing when they jump, and return to grazing when the light intensity is weak at 7 o'clock in the evening and affects the sight of the grazing chickens;

[0026] 2. Supplement high...

Abstract

The invention discloses a method for controlling locusts and raising poultry in high-altitude grasslands in the northwest areas, in particular relates to a method for controlling locusts and raising chicks in high-altitude grasslands, aiming at solving the problems of negative effects of the traditional locust controlling method on grassland ecological environment, biological diversity, health of poultry, food security and other aspects as well as poor locust control effect and high cost of the traditional locust controlling method. The method disclosed by the invention comprises the following steps of: 1, in the last ten-day of June each year, introducing table purpose Qingjiaoma chicks which are aged in 25-30 days in grazing grasslands where locust attack frequently happens and is severely harmful in winter and spring; 2, replenishing high-energy feed corns before the grazed chicks return every night; and 3, continuously grazing the chicks for 95-100 days in the grasslands and collecting all the chicks. The method disclosed by the invention is applied to the field of locust control and poultry raising in the grasslands.

Description

technical field [0001] The invention relates to a method for controlling locusts in alpine meadows and raising chickens. Background technique [0002] Meadow locusts have been regarded as pests that exacerbate grassland degradation and affect grassland ecological functions since ancient times. Global warming, prolongation of grass locust occurrence period, intensified human activities and irrational use of grassland resources all lead to grassland degradation and create favorable conditions for grass locust occurrence. The prolongation of the locust occurrence period and the increase in the population number together lead to frequent grassland locust plagues, which have a serious impact on the sustainable development of animal husbandry and the grassland ecosystem in the alpine-subalpine grasslands in the arid and semi-arid regions of Northwest China. For a long time, chemical control has been the first choice to control the number of locusts and alleviate locust damage. Ho...
