Embodiment 1
[0022] A method for biological control of root-knot nematodes using crop stalks rich in cyanogenic glycosides as a raw material, comprising the following steps:
[0023] A. After the crops are harvested, timely and thoroughly clean up the diseased plant residues and field weeds in the field, including the broken roots and branches of plants remaining in the soil, and centralize and harmlessly dispose of them;
[0024] B. Use a rotary tiller to level the land, deeply plow the soil by 300mm or 350mm or 400mm, and break up the soil mass above 10mm to make the soil loose, uniform and flat; water, spray or sprinkle water into the soil to maintain the soil moisture content of the plowing layer at 55% or 60% or 65% or 70% or 75%;
[0025] C. Grind the newly harvested cyanogenic glycosides rich in crop fresh straw with a water content of 30% or 40% or 50% or 60% or 70% with a pulverizer, and the particle size of the pulverized product is 10mm-20mm; use a rotary tiller , evenly mix it...
Embodiment 2
[0032] From late June to early September, when the crops are harvested, the diseased plant residues and field weeds in the field should be thoroughly cleaned up in time, including the broken roots and branches of plants remaining in the soil, and they should be treated in a centralized and harmless manner; use a rotary tiller Level the land, plow the soil 400mm deep, and break up the soil mass above 10mm to make the soil loose, uniform and smooth; water, spray or sprinkle water into the soil to keep the soil moisture content of the plow layer at 70%; freshly harvested corn stalks, Keep its water content above 50%, crush it with a grinder, and the particle size of the crushed material is 15mm; use a rotary tiller to evenly mix it into the soil cultivation layer of 400mm at an amount of 20kg per square meter; do ridges in the north-south direction , the height of the ridge is 500mm, the width of the bottom is 800mm, and the distance between adjacent ridges is 1000mm. One end of e...
