How to grow balcony vegetables?

The key techniques of growing vegetables on the balcony are as follows:

1. Balcony vegetable growing environment choice. (1) there should be all-day light: the sunshine time of different types of balconies is different. If the sunshine hours of the balcony are not enough for vegetables, not only the planting will be hard, but also the yield will be reduced; (2) the height of planting vegetables is better: the light of each part of the balcony is different, so the high potted plants on the shelf of the balcony can be arranged properly, so that they can have a better amount of light, or put iron window racks or hang flower racks to get more sunshine. (3) pay attention to the wind: the vegetable garden should be placed against the wall as far as possible, the relevant equipment should be fixed with ropes, and low vegetables should be selected to plant, so as to avoid the trouble of excessive wind.

two。 Balcony vegetable planting structure (professional equipment is recommended). (1) hanging type: set a hook at the top of the balcony or eaves, place thin steel pipes horizontally on the hook, hang the hanging basin on the pipe, or hang the hanging basin directly on the hook, in order to reduce weight, the hanging basin and cultivation quality had better be light. According to the actual needs, the hanging chain can be made of steel wire, hemp rope, nylon rope or color knitting material; (2) bearing wall type: basins or grooves can be hung on the wall. Hanging basin: inlaying expansion screws with hooks on the load-bearing walls, fixing steel pipes with hooks in the horizontal direction, and hanging light flowerpots on the pipes; (3) Wall trough type: planting grooves made of tin, etc., fixed on the wall with expansion screws, steel bars, etc., the trough can be equipped with light cultivation substrate. (4) column type: a steel pipe is placed vertically, a horizontal fixed seat is installed, and a micro-hole is drilled on the steel pipe every 5 cm or so, and the steel pipe is covered with a plastic tube, which is loaded into the cultivation substrate, the upper and lower ends of the plastic tube are pierced at the top and bottom, and the steel pipe is filled with water or nutrient liquid. A cultivation hole is drilled at a certain distance on the plastic tube to plant vegetables. Or the bottom of the central hole, set on the steel pipe, each flowerpot is fixed at a certain distance, inside the substrate for cultivation; (5) Box type: the use of wooden boxes, foam boxes, seedling trays for cultivation.

3. Balcony vegetable tools. (1) cultivation tools: small shovels, small rakes, small hoes, small boxes, etc.; (2) pruning and grafting tools: fruit tree shears, tweezers, sickles, etc.; (3) kidnapping materials: bamboo poles, wood bars, iron wires, plastic ropes, wire ropes, etc. (4) watering tools: spray pot, plastic pipe, bucket, micro water pump, etc. (5) cultivation containers: mud basin, glaze basin, porcelain basin, purple sand basin, plastic basin, etc., it is recommended to use professional containers.

4. The technical key of growing vegetables on the balcony. (1) selecting or cultivating strong seedlings; (2) cultivation substrate: it should have certain air permeability and water holding capacity; it can be recycled; (3) Water: water must be supplied in gaps or in part, so that the roots can absorb enough oxygen; it is best to absorb it from the bottom; do not overwater. Professional cultivation containers are generally able to strictly control water; (4) nutrition: organic fertilizer or plant nutrient solution, rest assured to use plant nutrient solution to supplement; (5) pest control: a variety of ways of combination, the appropriate use of pesticides, the key is to control the safe interval.

5. The basic principles of insect control for growing vegetables on the balcony. (1) giving priority to prevention, strictly disinfecting seeds and soil, strengthening management, reasonable fertilization and watering, (2) timely removal of leaves with diseased spots and yellowing, and increasing light as far as possible, regular ventilation and ventilation, in order to enhance plant photosynthesis and prevent the occurrence of flower drop, fruit drop and disease. (3) do not spray from the upper part of the plant when watering, it is best to put the flowerpot in the water at room temperature and infiltrate from the lower part. Plant into the peak period of human growth, that is, after the viewing period, fertilizer should be added in time, especially phosphorus and potassium fertilizer, in order to ensure the nutrients needed for plant growth; (4) insect control net, artificial weeding (eggs), supplemented by chemical control.

6. Some measures for the control of diseases and insect pests. (1) choose vegetables in season to improve crop growth; (2) choose various kinds and rotation: select various vegetables and use intercropping when planting; (3) garden planning or alternate planting of different crops to maintain ecological diversity, it will not lead to the occurrence of the same type of diseases and insect pests, convenient for regional control, and will not spread quickly. (4) maintain good ventilation: in the case of overcrowding, timely pruning can reduce the possibility of diseases and insect pests, but also maintain good ventilation and light; (5) cultivate repellent plants: spices, herbs or wild vegetables with strong odors are good for repelling insects; (6) use safe and reassuring natural pesticides: milk, beer, coffee, chili water, etc. (7) Natural insect repellent: edible oil, detergent, sugar and vinegar.
