Weeding method of bletilla striata

Abstract

The invention discloses a weeding method of bletilla striata. The method comprises the following steps of conducting sowing, wherein bletilla striata is planted from September to December every year, when planting is conducted, firstly land is prepared and ridges are dug, the width of each ridge is 1.2 meters, the length of each ridge is the natural length of farmland, the height is 20 centimeters, and the width of drainage ditches among the ridges is 20-30 centimeters; covering the drainage ditches with plastic thin film, wherein after bletilla striata is sowed, the drainage ditches among the ridges are covered with the plastic thin film, with the target that the thin film is wide enough to cover the two sides of each drainage ditch and the ditch bottoms, and the upper portion of the plastic thin film is covered with a little amount of mud, so that the plastic film is not blown by the wind; applying manure, wherein sheep manure or other animal manure is applied, in February to March of next year, when the bletilla striata sprouts for around 10 centimeters, 3-4 tons of manure is applied to each mu, and when the manure is applied, the sheep manure or other animal manure is applied to the periphery of bletilla striata; covering the farmland with bamboo bran, wherein 90% of bamboo bran and 10% of pulverized bamboo residues are uniformly mixed, the manure surfaces at the periphery of nursery stocks and the space among the nursery stocks is covered with the bamboo bran, each mu of the farmland is covered with 7 cubic meters of the bamboo bran, and the average thickness is 5 cm. According to the weeding method of bletilla striata, the labor and time are saved, the cost is low, and the weeding method of bletilla striata is efficient.

Description

technical field [0001] The invention relates to a plant weeding method, in particular to a method for efficiently weeding bletilla striata plantations with bamboo bran and plastic films. Background technique [0002] In the annual growth cycle of Bletilla striata, weeding is generally required about 10 times a year, 10 times per mu per year, and 70 laborers per mu for annual weeding, with a labor cost of 7,000 yuan. The first weeding is after the bletilla striata seedlings emerge, usually in April; from May to September, the bletilla striata grows vigorously, and the weeds also grow very fast. 7-8 days is a cycle, weeding once; each weeding It is necessary to hoe shallowly and loosen the border to avoid hurting the roots of Bletilla striata. At present, the weeding of Bletilla striata mainly relies on manual removal, and the labor cost is very high; there is also the use of herbicides for weeding, which will also increase the cost of planting. Both of these two methods have...
