Embodiment 1

[0027] Using the asparagus variety "Champion" as the material, the economic crop research in the Hebei Academy of Agriculture and Forestry Sciences

[0028] Implemented in the test field, introduce the continuous cropping asparagus cultivation method of the present invention in detail:

[0029] (1) Soil treatment: (1) Dig fermentation ditch: On May 4, 2014, after the destruction of the previous asparagus plants was completely removed, the previous asparagus plants were destroyed and selected as a field for planting. Draw a line in the middle of the row, mark the line, and dig a fermentation ditch with the line as the central axis. The depth of the fermentation ditch is 23 cm, and the width is 42 cm. The previous crop of asparagus in this plot was planted in 2006 and has been planted continuously for 8 years. In this example, in step (1), after the previous crop of asparagus is destroyed, it is selected as a field for planting. Before digging the fermentation ditch, the plant r...

Embodiment 2

[0048] Soil treatment: (1) Digging the fermentation ditch: After thoroughly removing the destroyed asparagus plants from the previous crop, select the planting field after destroying the asparagus plants from the previous crop, draw a line in the middle of the original 2 cultivation rows, and mark the changed line , taking this line as the central axis to dig a fermentation ditch, the depth of the fermentation ditch is 20cm, and the width is 45cm.

[0049] (2) In-situ fermentation of raw chicken manure: fill the fermented ditch obtained in step (1) with 10cm deep fermented product, the fermented product is: undecomposed raw chicken manure and straw according to the volume ratio of 7:3 Mix, wherein the straw can be replaced by wheat straw, and then add calcium phosphate and urea. The amount of calcium phosphate and urea added according to the total volume of raw chicken manure mixed with rice straw or wheat straw is calcium phosphate 10kg / m 3 , urea 2kg / m 3 . After the above...

Embodiment 3

[0064] Soil treatment: (1) Digging the fermentation ditch: After thoroughly removing the destroyed asparagus plants from the previous crop, select the planting field after destroying the asparagus plants from the previous crop, draw a line in the middle of the original 2 cultivation rows, and mark the changed line , taking this line as the central axis to dig a fermentation ditch, the depth of the fermentation ditch is 25cm, and the width is 40cm.

[0065] (2) In-situ fermentation of raw chicken manure: fill the fermented ditch obtained in step (1) with 15cm deep fermented product, the fermented product is: undecomposed raw chicken manure and wheat straw in a volume ratio of 7:3 Mix, wherein the straw can be replaced by straw, and then add calcium phosphate, urea. The amount of calcium phosphate and urea added according to the total volume of raw chicken manure mixed with wheat straw or rice straw is 12kg / m3 for calcium phosphate and 1.5kg / m3 for urea. After fully mixing the ...

Abstract

The invention relates to a cultivation method capable of overcoming continuous cropping obstacles of outdoor asparagus. The cultivation method includes following steps: 1, digging a fermentation ditchin the exact middle of two original cultivation rows; 2, filling the fermentation ditch with a fermentation material, spraying water, and fermenting, wherein the fermentation material is obtained bymixing decomposed raw chicken manure with wheat straw or straw according to a volume ratio of 7:3 and adding 10-12kg / m3 calcium phosphate and 1.5-2kg / m3 of urea according to total volume after mixing;3, pouring 10% difenoconazole wettable powder to an asparagus seedling culture bed where asparagus to be planted in a planting field is positioned, and planting asparagus seedlings; 4, applying an allelochemical inhibitor in each of 2-3d and 8-10d after planting; 5, after planting, pouring bacillus subtilis and difenoconazole wettable powder when withering asparagus plants are found. By the method, the problems of plant growth inhibition, disease and pest aggravation, yield reduction and quality deterioration after continuous cropping in conventional cultivation methods are solved.

Description

technical field [0001] The technical scheme of the invention belongs to the field of vegetable cultivation, and in particular relates to a cultivation method for overcoming obstacles to continuous cropping of asparagus in the open field. Background technique [0002] Asparagus (Asparagus officinalis L.), also known as Shi Diaobo, is a high-grade and valuable vegetable, known as the "king of vegetables". Asparagus is a perennial plant, once planted, it can be harvested continuously for 8-10 years. Asparagus is not suitable for continuous cropping. After continuous cropping, soil fertility will decline, diseases will intensify, plant growth will be inhibited, yield will decrease, and quality will decrease. This has become one of the bottlenecks restricting the development of asparagus industry. At present, there are few researches on the prevention and control products and technologies of asparagus continuous cropping obstacles. After the asparagus field is destroyed, asparag...
