The invention discloses a weeding composition containing cyhalofop-butyl and bensulfuron-methyl for paddy field, which comprises active ingredient a and active ingredient b, wherein the active ingredient a is cyhalofop-butyl, the active ingredient b is bensulfuron-methyl, the weight ratio of the active ingredient a to the active ingredient b is 1-90:90-1; preferably, the weight ratio of the active ingredient a to the active ingredient b is 1-50:50-1, and particularly preferred, the weight ratio of the active ingredient a to the active ingredient b is 1-10:10-1. The active ingredients of the composition account for 11 to 95 percent of the total weight of the composition, and the balance is agriculturally acceptable pesticide adjuvant.

The invention discloses a weeding combination and contains two active components of a and b, a is the compound of atrazine (N-2-ethylamino-N-4-isopropylamino-6-methylmercapto-1, 3, 5- triazine) with formula (I); b is a compound with the structure character of formula (II), wherein, R is H, Na, K or -C(O)-C3-C7alky, and X is Br or I; the weight ratio of a and b is 1: 0.07-9. The prevention effect of the herbicide made by the combination is better than the activity in the separate application of the herbicide a or the herbicide b, and the combination can bring surprising enhancing effect. The invention further discloses the application of preventing and eliminating the ruderal weeds in farmlands of corn, sugar cane, orange and other crops.

The invention relates to a synergist special for edible fungus and a preparation and use method thereof. The synergist special for the edible fungus comprises the following compositions by weight portion: 40 to 70 portions of treated fowl manure, 10 to 25 portions of calcareous shale, 5 to 35 portions of wheat bran and 5 to 10 portions of lime. The method comprises: adding 5 to 30 percent of pine needles and 0.1 to 0.5 percent of fermenting agent for deodorization according to the weight of dry fowl manure; adding water and uniformly mixing manure materials to control the water content of the manure materials to be between 55 and 65 percent, and performing stacking fermentation for 15 to 25 days at natural temperature; drying fermented fowl manure until the water content is less than 20 percent; and uniformly mixing the four compositions to synthesize the synergist. The amount of the synergist accounts for 10 to 30 percent of the weight of edible fungus cultivated materials, and the water content of the cultivated materials is between 55 and 60 percent. The synergist not only reduces the production cost and improves the yield of edible fungus but also reduces environmental pollution of the fowl manure, is favorable for normal growth and metabolism of hypha or fruiting bodies, has no toxicity, harm and potential accumulated toxicity on human beings and animals, and can be widely used for cultivating edible fungus such as oyster mushrooms, yellow oyster mushrooms, chicken leg mushrooms and branched oyster mushrooms.
