There are two ways to plant zucchini, one is to plant large and small rows, 80cm in big rows, 50cm in small rows, and 45 to 50cm in plant spacing; the other is planting in equal spacing, spacing in 60cm, plant spacing in 50cm, colonization in every 666.7 square meters. ~ 2200 strains. If the temperature is low after planting, small arch sheds should be covered in time, and if necessary, cold protection facilities such as haystacks can also be added.

1. Temperature management. After the planting period, the seedling stage was not ventilated, and was confined to raise the temperature, prompting the early rooting of the seedlings. During the daytime, the greenhouse temperature should be maintained at 25 to 30°C and 18 to 20°C at night. The temperature will be appropriately reduced after easing the seedlings. During the day, the temperature of the shed will be controlled at 20-25°C and 12-15°C at night to promote the development of the root system of the plants, which is conducive to female flower differentiation and early segregation. After sitting on the melon, the temperature is appropriately increased, and the temperature is maintained at 22-26°C during the day and 15-18°C at night to promote melon enlargement. After entering the period of fruit melons, the temperature gradually increases, and the ventilation volume must be gradually increased to extend the ventilation time. The maximum temperature during the day should not exceed 30°C.

2. Generally do not water during the slow seedlings, if the watering is not enough when planting, according to soil moisture pouring a small water. After easing the seedlings, control the watering before sitting on the roots. When the root melon sat and poured water, and with 667 square meters of water topdressing urea or compound fertilizer 10 ~ 15kg. After entering the period of fruiting melon, it is necessary to water according to the weather conditions and soil moisture in a timely manner, generally every 7 to 10 days, pouring water, each with water topdressing urea or compound fertilizer 10-15kg. Watering should be done as early as possible in the morning on sunny days. After watering, pay attention to ventilation and dehumidification, and use conditional drip irrigation and submerged membrane irrigation.

3. Plant adjustment and preservation of fruit. Due to the selection of dwarf early maturing cultivars for spring facility cultivation, it is generally not necessary to carry out vine-tightening and vine-tanning work during the growth process, and the old leaves, diseased leaves and yellow leaves should be promptly removed during the growth process. Due to the low temperature in spring and the hindering effect of facilities, pollinating insects are rare, and the monosomic fertility of summer squash is very poor. As a result, spring planting cultivation often results in flowering or melons due to poor pollination, which can be used for 30 to 40 ppm of production. Anti-declining smears female flower stalks for fruit protection.
