Fertilizer: From the perspective of cost-saving reduction of input and fertilization efficiency, 10,000 kg of chicken manure, 50 kg of urea, and 50 kg of ternary compound fertilizer are used per acre, which is the optimum amount of fertilizer for fruit and vegetable crops grown in greenhouses in coastal areas in Shandong.
Water saving: With drip irrigation, the relative soil moisture content is 80%, which is 70.4% more than that of conventional furrow irrigation. This is of great significance for the development of vegetable facilities in the saline-alkali areas where agricultural water is extremely lacking.
The main technical regulations:
1 Introduce fine varieties. Selection of low temperature resistant, weak light resistant, disease resistant, high yielding, and good quality mid-late ripe tomato varieties Israel 144.
2 nursery, colonization. The tomato seeds were soaked in water at 55°C for 10 minutes, then slowly lowered to 25°C to 30°C and soaked for 5 hours. Remove the drain and prepare the seedlings. When 5 to 6 leaves of seedlings are to be planted, the planting density is 2,000 plants per mu.
3 water and fertilizer management. With drip irrigation, when the relative soil moisture content is less than 80%, watering is performed to a relative moisture content of 100%. The results of the general period every 20 days topdressing once, each fertilizer can be controlled in the amount of urea per acre 5 to 10 kg, compound fertilizer 5 kg.
4 temperature management. After entering the result period, do not make the minimum temperature in the shed lower than 8°C. In the daytime, it may be properly ventilated if it exceeds 30°C.
5 plant adjustments. Single stalks are used for pruning to remove lateral branches at any time to ensure ventilation and light transmission in the field. Can be topping after the 5 ear fruit, in the upper part of the ear to select a strong lateral branch to replace the original main branch, can be left to 4 to 5 ear topping.
6 preserved fruit. Spray the flowers with the appropriate concentration of tomato spirits to ensure the fruit setting rate and artificial pollination.
Tof(Time-of-flight), is JRT new product, which is a single-point LiDAR 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. It's great for Unmanned Aerial Systems.Contact Us Now for data sheet.
