Early spring small arch shed zucchini is generally planted in the greenhouse in late February to early March, planted in late March to early April, harvested at the end of April, and harvested in mid-June. Now the growers of zucchini will start preparing for seedlings! 1, variety selection The varieties cultivated in the greenhouse, summer squash, and sorghum should be selected for rapid growth, early maturity and short planting. 2, seedling preparation The zucchini seedlings are made of nutritious alfalfa. The nutrient meal is made of waste plastic sheet or kraft paper, which is made of 12 cm in diameter and 14 cm in height, or directly purchased special nutrition in the market. 3, configure nutrient soil The nutrient soil is mixed with 50% of the pastoral soil, plus 30% of the decomposed ring fertilizer and 20% of the decomposed manure. Stir well and completely sieve. In addition, urea and superphosphate can be added as supplementary fertilizer. Then, fill the nutrient soil with the nutrients and make appropriate suppression. 4, soaking seeds and germination and sowing Before the sows are planted, the seeds are screened and aired. The hot water is simmered at about 55 °C, and the mixture is stirred until it is not hot. The duration is 20-30 minutes, and then the immersion in the clear water is 8-10. Hours, then the seeds are removed, and the appropriate rinsing, wrapped in wet gauze placed at 28-30 ° C for germination, about 2 to 3 days buds can be basically neat, and then can be sown. 5, seed preparation Organic zucchini should be poured into the nutrient water before sowing. After the water seepage, use a wooden stick to make a hole with a diameter of 2 cm and a depth of 6-7 cm in the middle of the nutrient bowl, and then place the seed of the good bud in the hole. Inside, one per hole, should not be placed upright, so as not to unearth the seeds in the future. After sowing, the sieved fine soil is covered or slightly raised, and the thickness is about 3 cm, and then the nutrient meal is placed one by one in the seedbed. 6, seedling management Due to the high temperature in the greenhouse during the autumn and winter cultivation of the greenhouse, the organic zucchini should be cooled after sowing, and bamboo rafts, wooden supports and other objects should be placed on the seedbed to cover the old grasshoppers, straw mats, etc., at noon on sunny days. Look back to cool down, avoid direct sunlight, to reduce the incidence of seedling virus disease, rainy days should be timely cover to cover, in order to prevent rain. Generally, at a temperature of 26-32 ° C, after 3-4 days, the seedlings can be basically released. 7, seedling colonization From the emergence of seedlings to the colonization of 25-30 days, it should be based on prevention of high temperature, prevention of seedlings and prevention of rain and water "three defenses"; at the same time, zucchini should pay attention to eliminate the media of viral diseases - aphids to ensure Miao Qi Miao Zhuang. When the seedling grows to 3-4 leaves, that is, when the seedling age is about 28 days, it can be colonized. The seedling age should not be too long, because the roots of the zucchini grow faster, the degree of lignification is higher, the root system is too large, and more roots are lost during transplanting, and the seedlings are slower. Now in the period of nursery, every grower can refer to the above suggestions for seedling work, and by the end of March, you can start planting.
