What do you need to pay attention to if you want to grow a gourd?

Zucchini is usually planted in spring and autumn, and can be planted in February-August. Planting methods and precautions are as follows:

1. Seeding and seedling raising?

Zucchini has strong adaptability and low requirements for soil and temperature. The suitable temperature for growth is 20 ~ 25℃, and the soil for sowing should be loose to keep fertilizer and water. In July and August, due to the high temperature, it is necessary to cover a sunshade net when sowing to cool the seedlings. First, select full cucurbit seeds and soak them in clear water for 12 hours, which is beneficial to germination.

Then take the seeds out of the water, and insert the small heads of the seeds into the sowing tray, with the row spacing of 5 cm and the grain spacing of 3 ~ 5 cm. After sowing, cover the seeds with 1 ~ 2cm soil, cover them with straw to keep them moist, then water them for 2 ~ 3 times to avoid uneven emergence, and then put them in the dark to wait for germination.

2. Water, fertilizer and pest management?

Zucchini bears a lot of fruits and needs a lot of fertilizer. Nitrogen fertilizer is mainly applied in the early stage, and phosphorus and potassium fertilizer are applied in the flowering and fruiting period. When the seedlings grow to 5 ~ 7 leaves, topdressing, covering and watering. After planting, some fertilizers should be applied in time, mainly decomposed cake fertilizer, and water should be poured once after planting to promote seedling delay. Water should be controlled after seedling stage is delayed and before fruit setting.

Generally, water is not used during flowering, and artificial pollination is used to promote smooth fruit setting. After fruit setting, topdressing and watering should be done in time, and then watering can be done properly during the fruit setting period. When the fruit grows to 3 ~ 4 cm in diameter, the second topdressing is carried out. If the water is insufficient, the small gourd will grow poorly, and watering generally follows the principle of not doing it and pouring it thoroughly. Powdery mildew, virus disease and aphid are the main diseases and insect pests in the growth of zucchini, so it is necessary to take timely control measures according to the related diseases and insect pests control methods.

Among them, powdery mildew is a common disease of small gourd. When it happens for the first time, 25% triadimefon 1000 times solution and 50% sulfur 150 times solution are selected and sprayed every 10 day for three consecutive times. ?

3. Planting skills?

Pinch the head: Because the gourd does not grow on the trunk of the small gourd, but bears fruit on the fork. Therefore, the lower bifurcation should be pinched off at the early stage of growth. When the main bud grows to 2 ~ 3 meters, pinch off the main bud and let the vine grow lateral buds at this height.

The small gourd treated in this way bears many fruits, and the small position is good after fruit hanging. Pollination: Brush the male flower core with a small brush, then brush it on the female flower core, or directly insert the male flower core into the female flower core. If there are bees or other insects, artificial pollination can be avoided.

But it is best to use artificial pollination, which can improve the fruit setting rate. Pruning: In order to keep the vine Ye Changqing of small gourd beautiful, the dead branches and leaves should be pruned in time, which can increase the appearance, improve ventilation and be beneficial to vine growth.
