The five points of spring squash breeding
Variety selection Choose disease-resistant, high-yield, high-quality, good-looking pumpkins of good appearance.
Soil preparation fertilizes the slightly acidic soil of the squash and the suitable pH is 5.5-6.8. Zucchini has a strong absorption capacity. Excessive application of nitrogenous fertilizers can easily cause stems and leaves to grow long, resulting in the occurrence of fruit drop and disease. Nitrogen, phosphorus and potassium should be used in combination with fertilization.
Sowing seedlings, whether using nursery seedlings or nutritional seedlings, must first be prepared with good nutrition soil, which is the key to nurturing strong seedlings. Take 3 fertile lands where no melons have been planted within 3 or 4 years, a decomposed rim fertilizer, a small amount of plant ash and sawdust, mix well, sifted, and then mash or mash, ready for use. Sowing, cover soil thickness 2 cm. After completing this work, a small amount of bran mixed with methamidophos should be sprinkled on the surface to prevent pests in the ground. Then, moisten with a small shed film until it emerges.
The standard for age-appropriate seedlings of Zucchini is about 30 days, with 3-4 true leaves, a plant height of about 10 cm, a stem diameter of 0.5 cm, a petiole length equal to the leaf length, a dark green leaf color, intact cotyledons, and a well-developed root system. .
The temperature during the seedling period is maintained at 20-25°C during the day and 10-15°C during the night. During this period, the water should be controlled scientifically and properly. In order to prevent the occurrence of blight, wilt disease and other diseases, a small amount of Wan Kui Guan Ling can be irrigated twice.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
