The invention discloses a supplemental
ditch planting method of vegetables, and aims at increasing the
fertilizer utilization rate and making root systems of the vegetables developed. The method comprises the steps that when
land preparation is conducted, base
fertilizer is not applied, and after land is subjected to rotary
tillage, field planting ditches are dug according to the planting spacingof the vegetables; fertilization is measured according to the size of the
ditch bottoms of the field planting ditches, 3-5 square decomposed cow
manure or 2-3 square decomposed
chicken manure and 50-55 kg of
phosphorus diamine are uniformly stirred and uniformly sprayed into the bottoms of the field planting ditches, and are fully and uniformly stirred with soil; supplemental ditches are dug at the portion 2 / 3 away from the sides of the field planting ditches, wherein the
ditch bottoms of the supplemental ditches is 1 / 3 higher than the bottoms of the field planting ditches; before field planting, the field planting ditches are watered with sufficient water, the
water depth exceeds 2 / 3 of the depth of the field planting ditches, so that the field planting ditches and the supplemental ditches are all filled with water; after water permeates thoroughly,
seedling strip matrix lumps are completely pulled out of plugs, and are pressed in bottom
sludge of the supplemental ditches according tothe
plant spacing required by vegetable field planting, so that the peripheries of the matrix lumps are in
close contact with soil, and the upper surfaces of the matrix lumps are slightly lower thanthe bottoms of the supplemental ditches.
