Peach tree fertilized in this way can increase sweetness and yield

When fertilizing the base fertilizer, it must be adapted to the distribution characteristics of the peach root system. The fertilization site was at the outer edge of the vertical projection of the canopy to induce deep root development. Sunlight greenhouses have a high density and can be ditched between plants and rows. It is advisable to ditch 45 to 65 cm deep. Fertilizer application rate is 60% ~ 80% of the annual application rate.

The application time and frequency of top dressing vary with species, soil quality, tree age, and tree vigor. The fertilization periods and types of fertilization during the year are as follows:

Fertilization before flowering is generally nitrogen-based, with an appropriate amount of phosphorus fertilizer to promote germination, make the flower tidy, increase fruit set rate, and increase the number of new shoots.

Topdressing in the hard core period This topdressing should be performed before the hard core of the peach, and topdressing with nitrogen-based compound fertilizer. Due to the development of the seed nucleus in the hard nucleus period, a large amount of nutrients are consumed, and timely fertilization can promote the development of the nucleus and the differentiation of flower buds, which not only improves the output of the current year, but also plays an important role in the output of the second year.

Topdressing outside the root can be applied throughout the year, but early peach growth is appropriate. The effect is usually seen within 10-15 days after application, but the effect disappears after 25-30 days. Topdressing outside the root is simple and easy, with a small amount of fertilizer, and it can play a fast role. It can timely replenish the urgent need of nutrients for peach trees, and can avoid the chemical and biological fixation of phosphorus and potassium in the soil.

Foliar spraying fertilizer The spraying time is best before 10 am and after 4 pm. Avoid spraying fertilizer at high temperature at noon to avoid fattening. In order to save labor and time, it can also be sprayed together with spraying.

Insect Sex Pheromone

Insect sex Pheromone as a chemical communication tool during the reproductive stage between allogeneous insects. The high complexity and specificity of its chemical structure is an important guarantee for reproductive isolation between insect species. Therefore, sex pheromones between different insects cannot The replacement will not cause confusion, which has great practical value in the regional investigation of insects, plant quarantine, and trap control.

In nature, adult females will release a compound called sex pheromone after sexual maturity. It is released into the air and diffuses with the airflow. It stimulates the chemosensory organs in the male antennae, causing male sexual impulses and lures. The male flies to the release source and mate with the female adult to reproduce offspring. Therefore, insect sex pheromone products are bionic high-tech products, which release artificial sex pheromone through the core.

Insect sex pheromone is a compound that regulates the attraction of male and female insects. It is sensitive and specific. It has a long distance and strong temptation. The use of this product to attract and kill pests does not contact plants and agricultural products, and there is no concern about pesticide residues. It is one of the first methods for controlling pests in modern agricultural ecology.

Currently the most popular insect sex pheromone varieties are: weevil sex pheromone, Asian corn borer sex pheromone, cotton bollworm sex pheromone, diamondback moth sex pheromone, glutenous sex pheromone, pear horde worm sex pheromone , Codling moth sex pheromone, soybean heartworm sex pheromone, cowpea viburnum sex pheromone, horsetail pine caterpillar pheromone.
