How do you train zucchini plants? A detailed explanation of three methods
Hanging and lowering the vines
Zucchini grown in open fields generally has stems and vines that creep along the ground. Greenhouse zucchini is planted at high density; to give the plants good light exposure, favor growth, and also facilitate pollination, spraying, harvesting and other field operations, the vines must be hung so the stems grow upright. When hanging the vines, first stretch a wire running north-south above each row. Use 1 string per zucchini plant, fix the lower end of the string to the ground with a wooden stake or tie it to the base of the zucchini stem, and as the vine grows, simply wind the string and vine around each other. A trellis method can also be used, that is, insert a thick bamboo pole beside each plant, then tie the vine with Chinese iris or plastic string. When tying the vines, be careful not to wrap the string around small zucchinis, and as you tie, adjust the plant's petioles so they spread out horizontally. Tying the vines should be done frequently; when tying taller individual plants, you can bend them so that the growing points are at the same height. If the growing period is long and the stems and vines are tall, the vines can be lowered appropriately.
Plant renewal
In greenhouse zucchini cultivation, the growing period is long, and the plants enter the aging stage in the later period. If the main vine ages or grows poorly, you can select and keep 1-2 side vines, and once they produce female flowers, cut away the original main vine to encourage the side vines to set fruit.
Promptly remove diseased, damaged and old leaves as well as side buds and tendrils
Zucchini leaves are large and the petioles are long, so they easily shade each other. Therefore, diseased and damaged leaves and the lower withered yellow old leaves should be removed as early as possible to avoid causing disease and consuming too many nutrients. Zucchini mainly sets fruit on the main vine, so the growth advantage of the main vine should be maintained and side buds should be removed as early as possible. For some young zucchinis that have partially turned yellow due to insufficient nutrient supply, remove them promptly to reduce nutrient loss and also avoid the spread of disease. Tendril growth also consumes nutrients, so tendrils should also be removed as early as possible. If there are too many male flowers in the middle and late periods, they should also be removed. After pruning branches and thinning leaves, spray agricultural streptomycin on the wounds to prevent the wounds from becoming infected.
