How to plant onions 1, soil preparation

Onions are suitable for growing in soil with rich humus and good drainage. When planting onions, it is necessary to plow 30 cm of soil to make it softer and more breathable, and then apply decomposed cake fertilizer or organic fertilizer to the soil to improve soil fertility and provide nutrients for onion growth.

2. Seed selection and seed soaking

When planting onions, we should choose bulbs with bright colors, full terminal buds and no diseases as seeds, then soak them in carbendazim 10 minutes for disinfection and sterilization, so as to reduce the infection rate of onions, and cut a hole in onions with a sterilization knife to make them emerge more easily.

3. Planting method

When planting onions, the top buds of bulbs should be buried upward in the soil, the depth of which is about two-thirds of that of onions, and then covered with a plastic film to raise the soil temperature and promote the rapid emergence of onions, and watered once every other week to keep the soil moist and make onions grow vigorously.

4. Topdressing

When planting onions, dilute human excrement and urine should be applied once after the plants emerge to speed up the growth of onions. Weeds in the soil should be pulled out in time to prevent weeds and onions from grabbing nutrients. In rainy season, the accumulated water in the soil should be drained for onions to make them grow healthily.
