Asparagus planting method

Abstract

The invention relates to the field of agriculture, in particular to an asparagus planting method. In the process of planting asparagus, according to the method, stellera chamaejasme, lonicera japonica, polygonum hydropiper, artemisia argyi, astragalus membranaceus and other plants are taken as raw materials, and are deeply buried in soil, and extraction liquids of stellera chamaejasme, lonicera japonica, polygonum hydropiper, artemisia argyi, astragalus membranaceus and other plants are sprayed at a whole asparagus planting garden and are used to smear whole stems, so that beneficial components in the plant raw materials are fully utilized, and give play to effects of dispelling and killing insects, killing bacteria and preventing diseases, and therefore the planting method, which does notneed pesticides, needs less chemical fertilizer usage amount and can obtain asparagus with higher nutrient content, is obtained. The asparagus obtained according to the planting method has relativelyhigh selenium content and vitamin C content.

Description

technical field [0001] The invention belongs to the field of agriculture, in particular to an asparagus planting method.

[0003] There are some defects in the existing planting methods of asparagus, which lead to thin diameter of asparagus, low yield, and easy occurrence of diseases and insect pests

Asparagus diseases mainly include stem blight, brown spot, sclerotinia, root rot, blight, rust and other diseases caused by fungi; insect pests include grubs, mole crickets, seed flies, needleworms and other underground pests and Spodoptera litura At present, pesticides are mainly used to prevent and control pests and diseases, which can easily lead to pesticide residues on the surface of asparagus tender stems. The surface of asparagus tender stems is scale-like leaves. The pesticides are not easy to wash off, and eating them will affect human health.
