Courgettes are aliased to melons, white melons, pumpkins, American pumpkins, Yunnan melons, melons, melons, and melons.
First, growth habits
1. Temperature The zucchini is a cold-tolerant, high-temperature type of melons and vegetables. The most suitable temperature for the growth period is 20°C to 25°C. The growth is slow below 15°C, and growth stops below 8°C. Slow growth above 30°C and prone to disease. The suitable temperature for seed germination is 25°C～30°C. It can germinate at 13°C, but it is slow. The germination is fastest at 30°C～35°C, but it is easy to cause leggy. A higher temperature is required during the flowering period, and it is generally best to maintain 22°C to 25°C. Early maturing varieties have stronger resistance to low temperature. The minimum temperature for root elongation was 6°C, and the lowest temperature for root hair was 12°C. Night temperature 8 °C ~ 10 °C fertilized fruit can be normal development. 2. Illumination The light intensity of the zucchini is moderate, and it is more resistant to low light. However, when the light is insufficient, it can cause leggy. Photoperiod is a short-day plant, long-day conditions conducive to the growth of stems and leaves, short-day conditions under the melon period earlier. 3. Humidity The zucchini is hi moist and does not tolerate drought, especially in the melon period soil should be kept moist to obtain high yield. Virus disease is prone to occur under high temperature and drought conditions; however, high temperature and high humidity can also cause powdery mildew. 4. Soil Zucchini requirements for the soil is not strict, sandy soil, loam, clay can be cultivated, the soil deep loam is easy to obtain high yield. 5. Pollination fruiting Zucchini is a pollen crop of male and female different flowers. Under greenhouse cultivation conditions, artificial pollination must be carried out. Pollination should be conducted every day from 9 to 10 am. During pollination, male flowers that are open on the same day should be used to remove the corolla and gently apply the stamens of the male flowers to the stigma of the female flowers to give pollen. Each male flower can grant 5 flowers. female flower. 6. The amount of fertilizer needed for the squash has a large amount of fertilizer. The production of 1,000 kg of commodity melon requires 3.9-5.5 kg of nitrogen equivalent fertilizer, 2.1-2.3 kg of phosphorus pentoxide, and 4-7.3 kg of potassium oxide.
Second, high-quality high-yield cultivation management
Before the spring sheds are planted, the zucchini must be fully prepared, such as careful preparation of the soil in advance, application of farmyard manure, mulching of the plastic film, and pre-planting seedlings. Per mu of sheds is full of 3,000 kg of high-quality farmyard fertilizer, 16-20 kg of diammonium phosphate, 20-25 kg of cake fertilizer, and 8 kg of potassium sulfate. After the fertilizer is applied, it will be turned deeper. Landing after deep plowing. The width of the ridge is 100 cm and the width of the ditch is 50 cm. Before the planting, a ditch with a depth of 15 cm and a width of 20 cm is opened in the middle of the ridge.
1. Determination of the planting period Determine the spring sheds when the cucurbit setting period is determined: refer to a principle: only when the minimum temperature in the greenhouse is above 8°C, and the ground temperature is stable at 10°C~l2°C, planting is safer. 2. Temperature Management Spring Greenhouse Cultivation of squash in the early stage of planting outside temperature is still very low, in order to promote rapid seedlings, to increase the temperature after planting, the daytime is 28 °C ~ 30 °C, when the temperature is higher than 30 °C, open a small tuyere, when the temperature is low Close the vent at 20°C. When the start of the growth of the leaf marks the end of the seedling period, the temperature can be appropriately lowered. The temperature is controlled at around 25°C during the day and 13°C to 15°C during the night. When roots sit and begin to inflate, raise the temperature appropriately. The whole growing period of the spring cucurbit squash cultivation is relatively short, and the growth and development process needs to be accelerated in order to obtain higher yield. After entering the result period, the temperature should be increased. The temperature should be 25°C to 28°C during the day and the minimum temperature should be maintained at 13°C to 15°C during the night. When the outside temperature is stable at about 12 °C ~ 14 °C, it can be ventilated overnight. 3. Top-dressing watering spring sheds Zucchini cultivation Due to the short growing period, high yields must be ensured. When the root melons are swollen, fertilizer is applied and 450 kg of ammonium nitrate is applied per hectare. After entering April, the outside temperature has risen. To produce pollution-free squash products and reduce the amount of chemical fertilizers, dilute manure water can be used, and about 7500 kg per hectare can be applied with water. Each time when watering, the human feces and urine are applied with water to ensure sufficient nutrients for plant and fruit growth. As a result, the frequency of topdressing and watering should be appropriately increased in order to increase the frequency of harvesting.

Plant extracts powder have the characteristics of green, environmental protection, and safety, and it has been emphasized in culture applications, and it has gradually become a research hotspot, and it has gradually become a positive and productive alternative to antibiotics after feed resistance prohibition.
Plant Extract (PE) is a single or mixed substance obtained from plants by physical and chemical means, which contains polyphenols, alkaloids, polysaccharides, essential oils and other active substances. Polyphenols are the most abundant active components of PE, which have antioxidant, anti-inflammatory, antibacterial and anti-tumor activities. Similarly, other components (e.g., flavonoids, alkaloids) have multiple biological functions.
The Catalogue of Feed Ingredients contains 117 natural plant extracts, such as anise oil, basil oil, cinnamon oil, clove bud oil, orange oil, lost essential oil, oregano oil, and thyme essential oil.
Plant extracts powder is rich in bioactive substances, which has the functions of regulating nutrient metabolism, antioxidant, immune regulation, antibacterial and insect repellent. It is a green and healthy additive, and has a good effect on promoting the healthy growth of piglets. It plays an important role in reducing the use of antibiotics and promoting the development of healthy aquaculture.
