Different ages of kiwifruit "recipes" differ

Young kiwi trees (1 to 2 years old trees)

Fertilizing saplings is mainly for the purpose of expanding the canopy as soon as possible, forming as soon as possible, and as soon as possible. Top dressing is mainly fast-acting nitrogen fertilizer. Followed by 2 to 3 times a year. Before the first germination, topdressing 50 g urea/strain, topdressing urea 50 g/strain during growth stage. After the kiwifruit tree growth status chase fertilizer material

Kiwifruit trees (3 to 4 years old trees) in the early fruit period

For this period of kiwifruit, it is still mainly plastic surgery. The kiwifruit at this time is dominated by vegetative growth, but it has begun to shift to reproductive growth. All trees have flowering results and have a certain yield. The following data can be used for fertilization: base fertilizer, 1500 kg of straw fertilizer or 1500 kg of livestock manure per hectare, 1500 kg of cake fertilizer, 750 kg of calcium phosphate fertilizer, 150 kg of urea fertilizer before bud application, 450 kg of compound fertilizer, or Potash 225 kg.

Kiwifruit fruit trees in the early fruit period (5-6 years old trees)

In this period, the kiwifruit tree shape has been formed and covered with a frame, the tree potential has begun to turn to the middle, and reproductive growth and vegetative growth have begun to balance.

During this period, the amount of fertilizer per hectare of kiwifruit was as follows: base fertilizer, 2400 kg of cake-fertilizer, 22,500 kg of livestock manure or 22,500 kg of straw manure, 1200 kg of calcium, magnesium and phosphate fertilizer, 225 kg of urea fertilizer or 375 kg of compound fertilizer, and strong fruit fertilizer. Apply 750 kg of compound fertilizer or 375 kg of potash; harvest fruit fertilizer, depending on tree vigor.

Kiwifruit tree in full fruit (6 years old or more)

During this period, reproductive growth and vegetative growth of kiwifruit were relatively balanced, which was the period when kiwifruit was produced with high quality and high yield. The fertilization amount per hectare of kiwi fruit in full fruit period is as follows: base fertilizer, 36,000 kg of cake-fertilizer, 30,000 kg of livestock manure or straw, 3,000 kg of calcium, magnesium and phosphate fertilizer; pre-bud fertilizer, 450 kg of compound fertilizer or 300 kg of urea; 900 kg of compound fertilizer or 450 kg of potash fertilizer; fruit fertilizers are applied according to tree vigor.

The types of fertilization materials can be determined according to the conditions of the source of fertilizer. When applying, according to the content of the active ingredients of different tree ages and different fertilizers, referring to the above-mentioned standards, the required amount of various fertilizers shall be calculated and fertilized reasonably.

Long Range LiDAR Radar

Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.

Highlights:

> Measurement frequency: 400 Hz (Max 60m 3000Hz)
> Long range: 200m
> High temperatures: -10~+50℃
> UART output
> Connector design: easy to use
