1. Fine site preparation. We can select rows of canopies, dry and pourable, breathable fields, and cultivate and plow land, combined with 5,000 kg of organic manure, 50 kg of compound fertilizer, and 5 kg of multi-element boron fertilizer. 1.2 meters wide.
2. Suitable sowing. Cucumber varieties should use high temperature resistant, glutinous, disease resistant, and high yield varieties. Such as Jinchun No. 4, Jinyan No. 4, Ludi No. 2 and Xiafeng No. 1 etc., which will be broadcast live around May 20th, with 2 lines per hole, 20 cm hole spacing, 3 seeds per hole, 5000 seed per mu. Around the hole, the width of the cover is 90 cm.
3. Field management. Melon seedlings immediately ruptured when the top membrane was unearthed. After the film has encountered dry weather, it should be watered one by one at night. After 7 days of seedlings, the seedlings will be seedlings, leaving 1 strong seedling per hole and pouring water once and then cultivating. Summer cucumber is shallower than spring cucumber cultivator, 4-5 cm can be. When the cucumber seedlings “mock their headsâ€, they are inserted into the brackets, and they are introduced in time to prevent them from intertwining and affecting growth. When tying the vines, the vines spread evenly on the racks, and the vines spread back to the top of the rack to extend the main vines and promote multi-fruiting. At the same time, the tendrils and the lower old leaves and diseased leaves are promptly removed. The weeds were cleared at the early flowering stage and the second cultivator was harvested before harvesting the root melons, 2 cm deep. After entering the melon period, over-summer cucumber grows vigorously, watering and rainfall are more, soil nutrient is easy to lose, so it should be more fertilizer, diligent watering, watering should be in the evening or morning, should not be watered at noon. In high-temperature and dry weather, watering once every 1-2 days, 20 acres of urea topdressing. In order to prolong the melon period, 100 grams of potassium dihydrogen phosphate per acre can be used to spray 50 kilograms of water on leaves, and sprayed once every 3-5 days. It is also possible to spray multi-faceted compound organic fertilizers on the leaves and spray the leaves 3 times.
4. Harvest in time. In summer, the temperature is high, the plants grow fast, and the fruit develops quickly. Generally, it can be harvested 50-60 days after sowing. When harvesting, it is advisable to collect early ground income in order to avoid crashing. Generally, it is harvested every other day. The melon period can be harvested every day to ensure that the melon strips are fresh and grow vigorously.
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.
