Embodiment 1
[0050] Embodiment 1 A kind of planting method of white asparagus with high rate of primary bamboo shoots
[0051] The cultivation method sequentially comprises the steps of raising seedlings, planting, garden clearing, film covering, simple harvesting of white asparagus and field management after harvesting the bamboo shoots.
[0052] Step 1. Seedling cultivation
[0053] Select "Shuofeng", "Grant", "Atlas" and other varieties suitable for planting white asparagus, and use plastic greenhouse nutrition pots to raise seedlings in early January, and select seedlings when the seedling age is 80d~90d Seedlings with a height of 30 to 35 cm and more than 3 aboveground stems and more than 7 underground storage roots are used for field planting.
[0054] Step two, colonization
[0055] One week before planting, dig a planting ditch according to the topographic trend. The width of the planting ditch is 1m, the depth is 0.5m, and the distance between the sidelines of two adjacent...
Embodiment 2
[0083] Embodiment 2 A kind of planting method of white asparagus with high rate of primary bamboo shoots
[0084] Adopt the step of embodiment 1, only change step 4: cover film, carry out the operation of embodiment 2;
[0085] Step 4 of Embodiment 2: the coating is:
[0086] Step 4, lamination
[0087] After clearing the garden, begin to cover the film in mid-March, and the film is an astigmatism heat insulation thermal radiation regulation film.
[0088] First, use stainless steel pipes to build a large arch shed in the bamboo shoot field. The specifications are that the vertical height on both sides of the large arch shed is 1m, the height in the middle is 2m, and the width of the large arch shed is 3.5m;
[0089] Plant 4 rows of asparagus in the big arched shed, and the distance between the side row of asparagus and the outer edge of the shed is 0.5m;
[0090] The shed is covered with astigmatism, heat insulation and heat radiation control film, and the film is fixed ...
