Peanut growth at the late stage of growth protects the fruit

The late stage of peanut growth refers to the period from the later stage to the full ripe stage, lasting about 50 days, which is the main period for increasing fruit weight. Its management focuses on protecting leaves and preventing decay. The main measures are as follows.
Spray fertilizer to protect the leaves of the plant to enhance the vitality of leaves, extend the functional period of the leaves, from about 40 days after flowering, every 10 to 15 days, spraying potassium dihydrogen phosphate (concentration of 0.2% to 0.3%) and urea (concentration of 1% ~ 2%) of the mixture of 50 kg, continuous spraying 2 to 3 times.
The water requirement of reasonably controlled water peanuts at the later stage of growth is reduced, and the suitable soil moisture content is 50% to 60% of the maximum water holding capacity in the field. In case of drought, sprinkler irrigation or small-water rapid furrow irrigation shall be sufficient, and flood irrigation shall not be allowed; timely drainage in case of heavy rain. Avoid watering two weeks prior to harvest, as ripe fruits may already be present at this time. Poorly moist fruits in the field tend to germinate or be contaminated with Aspergillus flavus.
Control pests (1) leaf spot. Occurs in the pod enlargement period. In the early stage of disease, 50% carbendazim WP can be used 600 times, or 96% DF WP 3000 times, or 70% thiophanate WP can be 600 times. Spray, spray once every 10 to 15 days, continuous control 2 to 3 times. (2) Hey. It can use the phototaxis of adult chafers and trap it with insecticidal lamps. Chemicals to control larvae should be mastered during egg incubation period and young larvae stage, with 48% chlorpyrifos microcapsule suspension 250-400 ml/mu, mixed with fine slag or coarse sand 20-25 kg Kaiqi points, immediately after application Watering, or adding water 40 kg spray irrigation roots. It is also possible to use 1 to 1.5 kilograms of 40% phoxim EC per acre, and pour with water after the evening.

Small 2D LiDAR Sensor

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.
