How to Grow Winter Greenhouse Zucchini? Detailed Guide to Planting and Management Techniques

Zucchini requires relatively strong light, so in practice, you can take measures such as uncovering the straw curtain early and lowering it late, wiping the drip-free greenhouse film every 3~5 days, removing grass debris and dust from the film, and hanging reflective film on the back wall inside the greenhouse to increase the light intensity inside; if there is continuous rainy or snowy weather, you can spray light film fertilizer, which can help growing plants absorb light energy, boost vitality, nourish with rain and dew, and grow strong. For fertilizer and water management, when the first fruit has set and grown to 10 cm, you can water a second time. After that, zucchini will gradually enter the peak fruiting period, and in greenhouse management you should apply fertilizer and water according to the weather and plant development.

For hanging and trellising vines, stretch a thin steel wire north-south 1.8 m above each row of zucchini, tie one hanging string to each zucchini plant, with the upper end tied to the thin steel wire, and the lower end tied to the zucchini must be tied with a slip knot, so that after the plant sets fruit it will not lean and fall to one side. Also, during the young fruit stage and expansion stage, spray Zhuanggua Diling to enhance the plant's water and fertilizer absorption capacity and the yield and quality of the fruit, reduce the fruit drop rate, and decrease the incidence of cracked fruit, stiff fruit, and deformed fruit. When hanging vines, keep one main shoot per plant and remove the other axillary buds early. At the same time, regularly remove the old leaves at the bottom that have lost function and turned yellow, to reduce nutrient consumption. During the growth process, zucchini tends to produce many tendrils; to save nutrients, the tendrils should also be removed early.
