The high-yield cultivation method comprises the following steps that
sowing and
seedling raising are carried out on a
land parcel with good drainage and
irrigation conditions, seeds of the
kenaf germinate for three days and grow slowly in the
seedling stage, when the seedlings reach 25-30 cm,
thinning and ridging can be carried out on the
kenaf in 2-3 times, finally, final singling is carried out on 90000-1200000 plants / hm < 2 >, and the seedlings are planted in a high-yield mode. During
sowing, base
fertilizer is applied with an
organic fertilizer of 3000-6000 kg / hm < 2 > and a compound
fertilizer of 150 kg / hm < 2 >, topdressing is properly carried out in the
seedling stage according to the seedling condition, in the vigorous growth stage from June to July, nitrogenous
fertilizer is mainly applied,
phosphorus-
potassium fertilizer is used as an auxiliary fertilizer, potherb vegetables are harvested once every 7-10 days after
topping, after each time of harvesting, compound fertilizer of 150-225 kg / hm < 2 > and
urea of 75-150 kg / hm < 2 > are properly applied once, lateral
bud germination and
branch growth are promoted, and soil is kept moist. The invention provides a scientific and efficient cultivation method for high-
calcium potherb vegetable, which not only improves the yield and quality of crops, but also gives consideration to both economic benefit and
environmental protection, and has important application value and
social significance.
