The latest course of asparagus high-yield and pollution-free planting techniques

Asparagus is a kind of vegetable with high nutritional value in China, which has a very wide planting area in our country. Nowadays, Chinese people have higher and higher requirements for vegetables, so new pollution-free high-yield planting techniques of asparagus have gradually emerged. While ensuring the output, it can also prevent pesticides from exceeding the standard. So how exactly should we do it? The following editor has brought you the high-yield and pollution-free planting technology of asparagus. Let's have a look!

1. Selection of species and sites

The relationship between variety and asparagus yield is very high, so we must make a good selection of asparagus varieties before planting asparagus. Reasonable selection should be made from various aspects such as production performance, quality and stress resistance. Then is to do a good job of site selection, pollution-free planting can be planted mainly under the forest, so we had better choose poplar forest, pay attention to diseases and insect pests, plant spacing is controlled at about 5 meters. The terrain can not be low-lying, to ensure convenient transportation, and finally to ensure that the soil fertility, permeability and normal drainage and irrigation.

2. Soil preparation and trenching

Be sure to do a good job of soil preparation before planting asparagus, level the soil, and then turn it about 35 centimeters deep. Ploughing the soil repeatedly to ensure that the soil is loose enough, the ground is clean and permeable, to ensure the normal growth of asparagus, and then apply appropriate amount of base fertilizer according to the planting area. Then control the planting density of asparagus and dig the planting ditch, when the poplar forest is planted, the planting area of asparagus can reach about general. The depth of the planting ditch is maintained at 35 cm, depending on the quality of the soil.

3. planting at the right time

It should be the best time for asparagus transplanting before and after Ching Ming Festival every year. Because at this time, the scale bud disk of asparagus has not yet fully sprouted, the root ability of asparagus is relatively poor, and the new root has not yet fully developed. Therefore, if the seedlings are transplanted at this time, the survival rate is high and the yield is obviously improved. When planting asparagus, the depth should be controlled at about 9 cm. Then the asparagus is planted and the soil is filled on both sides. This can promote the horizontal development of asparagus and effectively increase the yield.

4. Strengthen the management

To plant asparagus, we first need to do a good job in the management of water and fertilizer, and we should reasonably adjust the fertilization time and amount according to the growth of young stems of asparagus. At about 10 cm, start the first time of water and fertilizer, dig the fertilization ditch about 20 cm away from the plant, and cover the soil. Then according to the actual situation to do a good job of watering, in less water areas about 10 watering once. Finally, it is necessary to do a good job in the management of weeding and pest control, and only by strengthening the management can we ensure the better growth of asparagus and increase the yield.

The above is a brief introduction of high-yield and pollution-free planting techniques of asparagus. Asparagus is very popular, but when we increase the output, we also need to pay attention to ensuring the quality, so we must pay more attention to it. That's all for today's introduction.
