First, choose the right variety
Spring sowing garlic from the species to receive about 100 days, the whole growth period is very short, we must choose the winter is weak, the growth period of short varieties. Some varieties with longer growth periods can also be used for spring sowing if they are adapted to high temperature conditions in the middle and late stages.
Second, re-base fertilizer
A month or so before planting, combined with a high-quality manure manure or manure 3,000 kg, 100 kg cake fertilizer. A week before sowing Mushi 45.6% compound fertilizer 50 kilograms, smashing flat, so that the soil is fully mixed, smashing to be broadcast.
Third, timely early broadcast
Spring sowing garlic soil as soon as possible after sowing, sowing too late can not accept the vernalization process, and finally the formation of little garlic and single head garlic.
Fourth, strengthen seedling management
The spring seeding garlic seedlings have a short growing time, and they should be topdressing and watering on the basis of applying base fertilizer. After May, the temperature gradually rises. Watering in time is the key measure in field management. Don't flood the entire seedling stage. It should be done with a small amount of water and a small amount of water. The soil temperature should be raised to increase the ground temperature. In the cultivator, the first water is poured at the 6th leaf stage, and the water is poured once every 5 to 7 days to keep the soil moist. When the seedlings are cultivated, they are combined with watering, and 75kg of cakes or 20kg of ammonium bicarbonate can be applied to the harvest. After the garlic is returned to the garlic, it enters the elongation period of garlic sprouts. The period of symbiosis between garlic sprouts and petals is the period when the most water and fertilizer are needed. This period top dressing 1 to 2 times, per acre can be applied to human waste 1000 to 2000 kg, every 7 to 10 days to recover urea 15 to 20 kg. Pour water once every 4 to 7 days to keep the soil moist. Stop watering 3 to 4 days before picking, so as not to break the tender garlic and jade when picking. After the picking of garlic, the growth of roots, stems, and leaves tends to decline, and garlic grows into the prime period. The average daily gain of garlic is 1 gram. After the picking, it should be watered once, and nitrogen fertilizer can be chased once. Afterwards, the water should be poured every 3 to 5 days to keep the soil moist. Stop watering 5 to 7 days before collecting garlic to harvest.
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.
