Embodiment 1

[0027] Taking the asparagus variety "Champion" as the material, and taking the saline-alkali land experimental field in Haixing County, Hebei Province as an example, the cultivation method of asparagus in saline-alkali land is introduced in detail:

[0028] (1) Soil treatment: The salt content of the 0-10cm soil in the test field is 0.64%. Lay polyethylene perforated pipes (PVC concealed pipes) at 60-80cm underground in the field with a spacing of 10m; install a pipe every 20m vertically to the ground Drainage ditch, 0.8-1m deep and 1-1.2m wide (if attached figure 1 ). Before April 5th, the fresh water pressure salt will be carried out, and the water consumption will be 120m 3 / mu. Before April 20th, prepare the ground carefully for planting. When preparing the land, spread 5 square meters of organic fertilizer, 50 kg of superphosphate, 25 kg of urea, and 5 kg of potassium sulfate per mu. Deepen the soil by 30 cm, level the plot, and irrigate the entire border. The slope is...

Abstract

The invention relates to a method for cultivating asparagus in the seashore saline land, and belongs to the field of vegetable cultivation. The specific method comprises the steps: choosing strong salt resistance asparagus varieties, such as ' Apollo' and 'Champion' asparagus varieties, taking saline-alkali soil with the salt content of 0.1%-0.2% as the matrix, growing seedlings in feeding pots in early August, and paving the wheat straw on ridge faces after planting to prevent accumulation of salt in the surface soil; carrying out field planting in late April the next year, and storing fresh water for leaching 15-20 days before field planting; ditching and carrying out field planting with the line spacing of 1-1.2m, and the row spacing of 25cm, digging deeply and burying shallowly, and harvesting rainwater in furrows for freshwater irrigation; after field planting, covering the mulching film between ridges to prevent accumulation of salt in the surface soil. The asparagus is harvested in a way that the stem is reserved and topping is carried out to prevent lodging when the stem is 1.5m. By applying the method for cultivating asparagus in the seashore saline land, the problems of seedling missing, seedlingless ridges and low survival rate in the traditional cultivation technique are solved, and the high and stable yield is realized . The technology is suitable for being applied in the seashore saline land with the soil salt content 0.4% to 0.8%, the survival rate is increased by more than 20% compared with that by the traditional cultivation technique, and the yield is increased by more than 30%.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a method for planting asparagus in coastal medium-severe saline-alkali land. Background technique [0002] Asparagus is a high-grade nutritious and healthy vegetable that is popular among consumers. It is tender and delicious, rich in nutrition and unique in flavor. It is known as the "King of Vegetables". There are a large number of saline-alkali lands in my country, and asparagus cultivation in saline-alkali lands can not only realize the improvement of saline-alkali lands, but also alleviate the contradiction between vegetables and food for land. Generally speaking, in the cultivation of plants on saline-alkali ground, the normal growth of halophytes can be achieved by using fresh water pressure salt, mulching, and application of salt-tolerant varieties. However, this conventional technology is only suitable for asparagus with a salt content of 0.3%. Under mild saline-...
