What planting density is suitable for zucchini?
SummaryThe recommended planting density for zucchini is a plant spacing of about 80cm, a row spacing of about 140cm, and about 800-1000 plants per mu is relatively suitable. The specific planting density can be determined according to the variety of zucchini seedlings and the specific growth conditions of the zucchini. If it is a variety with a larger plant type and robust growth, it can be appropriately planted more thinly.
I. Planting density of zucchini
When the zucchini seedlings have grown enough to be transplanted, they should be transplanted in a timely manner. The transplanting density should be determined according to the variety and growth conditions of the zucchini seedlings. If it is a variety with a larger plant type and robust growth, it can be appropriately planted more thinly. The recommended plant spacing is 80cm, the row spacing is 140cm, and generally about 800-1000 zucchini plants are transplanted per mu.
II. How to achieve high yield in zucchini
1. Site selection and seed selection
(1) Zucchini has a certain drought tolerance, but it is relatively afraid of waterlogging, so zucchini is suitable for planting on loose-textured sunny slopes.
(2) Before planting zucchini, it is necessary to understand whether the previous crop conflicts with it, and also to check for the problem of pesticide residues.
(3) In addition, when choosing zucchini for planting, choose excellent varieties that are early-maturing, high-yielding, and fast-growing. If conditions permit, it is best to choose the early-maturing first-generation zucchini hybrid variety with vine-trailing characteristics.
2. Sowing and seedling raising
(1) Before sowing, the seeds should first be treated to increase the germination rate. First, the seeds should be sun-dried and soaked in warm water, or dressed with chemicals, to avoid the seeds carrying pathogens, reduce diseases during the seedling stage, and promote robust seedling growth.
(2) The sowing time should be determined according to the local climate and planting season. There are also strict standards for the sowing rate. Generally, about 400 grams are sown per mu, with a sowing depth of 3 cm. After sowing, fertilizer and pesticide should be applied in a timely manner to eliminate weeds.
3. Fertilizer and water management
(1) Zucchini has relatively strong drought tolerance, so its water requirements are not very high. In the early stage, water once when preparing the land, and later watering can be combined with fertilization.
(2) Zucchini fertilization is mainly based on organic fertilizer, and nitrogen, phosphorus, and potassium fertilizers are all acceptable. During the seedling stage, zucchini can be watered once and topdressed once with urea, which helps the seedlings recover.
(3) In addition, water and topdress once when the fruit sets, to ensure nutrient supply during fruit setting. In the full fruiting period of zucchini, fertilizer and water management is especially important, requiring watering and fertilizing once every half month.
4. Field management
(1) Field management of zucchini mainly includes intertillage and weeding, temperature and light management, artificial pollination, and so on.
(2) Generally, intertillage and weeding are carried out twice a year. The first time is at the seedling stage, when the seedlings have grown to about 20 cm, and the second time is when the zucchini has grown 5-6 leaves.
(3) During the flowering and fruiting period, the temperature must not exceed 30°C, and the nighttime temperature must not be lower than 15°C, otherwise it will affect the yield of zucchini. In addition, sufficient light should be maintained. If there is long-term rainy weather, artificial supplemental lighting can be used.
