Key recent management focus for zucchini: controlling excessive vigor
Recently, when visiting the countryside, I saw that the zucchini grown in greenhouses by vegetable farmers was generally growing too vigorously, and the plants were setting fruit poorly. When asked why, many vegetable farmers told the reporter: "The weather forecast earlier said this year would be a cold winter, so we thought temperature control alone would be enough to manage plant growth well and avoid excessive vegetative growth. If we also used plant growth regulators, it would very likely seriously affect the growth of the zucchini, so we did not use regulators. But unexpectedly, although the outdoor temperature this year was not high, the weather was clear and fine, and the temperature inside the greenhouse was relatively high, which caused severe excessive growth of the zucchini."
