At present, there are many ways to grow beans, and the practice of hanging beans in winter beans can better improve the ventilation conditions. Compared with traditional bamboo trusses or twigs, the use of plastic ropes to carry forward hangers has the following main advantages: : The first is simple and convenient. No matter whether it is at the front edge of the greenhouse or in the lower part of the arched canopy, it is convenient for a single row of forward hangers and vines. The second is to improve the ventilation and light transmission. By moving the antegrade wire that is tucked in the east-west direction to tighten the wire, the distance between the rows of hangers can be adjusted. By moving the distance between the slings on the anterograde wire, the adjacent vines can be adjusted. the distance between. In order to adjust the distribution of the main body of the pod vine, in order to improve the light and ventilation (gas) conditions. Nylon rope (line) or plastic film slings are all light-transmitting, which does not affect shading crops. The third is that the hanger is more suitable for three-dimensional cultivation of bean pods in greenhouses. The fourth is to facilitate the "zigzag-shaped" hangers. It is advisable to set up the hanger before the bean sprouts are thrown. The specific approach is: When the bean pods extend to 20 to 30 cm, artificial vines should be set up to aid the shelves. In Shouguang type winter warm plastic greenhouses, there are three east-west tension wires (24th or 26th steel wire) used exclusively for hangers. On the east-to-west stretched hanger wires, the north and south beans are placed on the shelf. Line spacing, set the gantry hanger wire (usually with 14 wire). On the anterograde wire, use the nylon or plastic film rope hanging from the line near the ground to hang the rope. The lower end of the sling is anchored on a short bamboo pole inserted deep between the plants. The short bamboo pole is 20-30 cm above the ground. The density of planting beans in greenhouses is 2,500 per acre, with 4 trees per acre and a total of 10,000 trees. When a hanger is used, two similar trees can be used with one sling, and one sling can be used for each tree. When artificially climbing the vine on a hanger, the bean stem vines can be easily tied to the slings. Pay attention to the frequent viewing after throwing vines, artificially assisting to spin the bean seedlings that failed to self-climb on the slings to the ropes. When the vines are put on the shelf, because the humidity in the greenhouse is high, the vines are delicate, and they are easy to break, they should be selected at noon on sunny days or in the afternoon. Avoid clouds on the cloudy days or in the morning.
