What should be noted when growing zucchini? Here is a detailed introduction. When growing zucchini, note the following points: 1. Sowing time. Sowing time should be determined according to the local climate and the cropping season.

When growing zucchini, note the following points:
1. Sowing time
Sowing time should be determined according to the local climate and the cropping season. For a greenhouse autumn-delayed crop, sowing in mid-September is suitable; for a winter-warm greenhouse overwintering crop, sowing in late October is generally suitable; for the winter-spring crop (following an autumn-delayed tomato or other vegetable crop), early to mid-November is suitable; for the early spring crop, sowing around New Year's Day is suitable.
2. Careful seedling raising:
Place the nutrient pots in the seedling bed and water them (32-cell plug trays can also be used for seedling raising). It is best to water the nutrient soil thoroughly. After the water in the pots has completely seeped down, dig a small hole about 2.0 cm in diameter and 1.0 cm deep in the center of the nutrient soil, and place the seed flat in the hole. Be sure not to insert the seed upright, so as to avoid seed hypoxia and seed rot. For the late-winter crop and winter-spring crop, it is recommended to water in the morning and first cover with an arched film to raise the ground temperature, then sow in the afternoon. The covering soil should be about 1.0 cm thick; too deep or too shallow covering soil will affect the uniformity and vigor of emergence. After covering with soil, cover with an arched film to help raise the ground temperature. After emergence, remove the arched film to harden the seedlings and cultivate strong seedlings.
3. Planting density:
Large row 100 cm, small row 80 cm, plant spacing 70-80 cm, plant 800-1000 plants per mu.
4. Management before fruit set:
Water once more 7-10 days after planting to promote seedling growth, help the plants grow vigorously and cultivate strong seedlings, and lay a good foundation for later high yield. Generally, do not water again before fruit set. When the plant grows to 10 leaves, spray zucchini regulator (this variety should be sprayed 2-4 leaves later than other varieties) for chemical regulation to prevent excessive vegetative growth. Because this variety sets fruit early and has dense fruit nodes, it is recommended not to keep fruit before 8 leaves for spring and autumn crops, and not to keep fruit before 10 leaves for overwintering crops. Before keeping fruit, the plants should be cultivated to reach the standard of thick stems, short internodes, large leaves, thick leaves, and vigorous and strong growth; otherwise, weak plant growth will seriously affect mid- and late-stage yield. When the plant grows to about 15 leaves, depending on the plant's vigor, spray zucchini balance agent once more. This makes the plants strong but not excessively vegetative at the early fruit stage, with vegetative growth and reproductive growth in harmony. After fruit set is complete, water once with a fruit-swelling irrigation.
