Embodiment 1

[0020] Taking the asparagus variety "Champion" as the material, the asparagus cultivation method is introduced in detail in the experimental field of Wei County, Hebei Province:

[0021] (1) Seedling cultivation: On April 7, 2009, the asparagus seeds were germinated and single-grained on-demand into the nutrient pot. The amount of seeds used per mu was 90-100 grams, under conventional management, and the seedling age was 60-70 days for colonization.

[0022] (2) Soil preparation: Evenly spread 3 tons of high-quality organic fertilizer and 40 kg of N-P-K (15-15-15) compound fertilizer per mu on the pre-cultivated asparagus field, and plow the whole field 35 cm deep to make the raw soil, mellow soil, Mix organic and chemical fertilizers thoroughly.

[0023] (3) High-density planting: planted on June 10, 2009, and planted with a row spacing of 0.9 meters and a plant spacing of 22 cm.

[0024] (4) Topdressing: 1 month after planting combined with watering, topdressing urea 10 kg ...

Embodiment 2

[0031] Taking the asparagus variety "Jessie Knight" as the material, the asparagus cultivation method is introduced in detail in the experimental field of Wei County, Hebei Province:

[0032] (1) Seedling cultivation: After the asparagus seeds are germinated, a single seed is sown on-demand in a nutrient bowl, the amount of seeds per mu is 90-100 grams, conventional management, and the seedlings are planted in 60-70 days.

[0033] (2) Soil preparation: Spread 4 tons of high-quality organic fertilizer and 50 kg of 45% N-P-K compound fertilizer evenly per mu on the pre-cultivated asparagus field, and plow the whole field 40 cm deep to make raw soil, mellow soil, organic fertilizer and chemical fertilizer fully Mix well.

[0034] (3) High-density planting: planting in large and small rows, with a large row spacing of 1.5-1.6 meters, a small row spacing of 40-50 cm, and a plant spacing of 22 cm.

[0035] (4) Topdressing: 1 month after planting combined with watering, topdressing ...

Abstract

The invention relates to a dense planting dwarfing high-yield cultivation method of green asparagus, which belongs to the field of plant cultivation and is mainly used for increasing the yield of green asparagus in 2-5 years after planting. This method is to increase the land utilization rate by increasing the planting density, shorten the row spacing of the traditional cultivation method from 1.4-1.5 meters to 0.8-1.0 meters, or plant in large and small rows (large row spacing 1.5-1.6 meters, small row spacing 40-50 cm), The distance between plants is 20-25 cm, 2800-3000 plants per mu; dwarfing pruning is carried out, and the mother stem is 1.1-1.2 meters topping to prevent lodging. At the same time, increase the amount of fertilizer to achieve the effect of increasing production and improving planting efficiency. Cultivation by this method can increase the output of green asparagus by 30%-50% in 2-5 years after planting.

Description

technical field [0001] The invention relates to a cultivation method of asparagus, in particular to a dense planting dwarfing high-yield cultivation method of green asparagus. Background technique [0002] Asparagus is a high-grade nutritious and healthy vegetable that is loved by consumers. It is tender and delicious, rich in nutrition and unique in flavor. It is known as the "king of vegetables". Asparagus is a perennial plant, which can be harvested continuously for 8-10 years after planting in one year. In recent years, asparagus stem blight, as a devastating disease, has spread in northern asparagus producing areas, especially in bamboo fields over 6 years old. Cause the destruction of the whole field, and stem blight occurs relatively lightly in the 2-5 year old bamboo shoot field, so how to improve the output of the 2-5 year old bamboo shoot field is an effective way to improve the asparagus planting benefits. In conventional green asparagus cultivation, the planting...
