Embodiment

[0017] Stipa grandis was chosen to be interplanted in the urban gardens of Tianjin Binhai New Area. Tianjin Binhai New Area is located in Bohai Bay, especially in Tanggu and Dagang.

[0018] The cultivation method of Stipa grandis comprises the following steps:

[0019] 1) Cultivation site selection: choose urban broad-leaved forests in saline-alkaline areas for planting, with an altitude of 2-5 meters; choose Stipa grandis seeds, with a germination rate greater than or equal to 85%; apply 300kg of landscaping organic fertilizer or fermented organic fertilizer from urban tree branches before sowing / mu, avoid trees and deeply plow the soil 50cm, mix with 20% river sand based on soil weight in the upper layer of soil, and then carry out site preparation to make the land reach the state to be sown;

[0020] 2) The sowing time of Stipa grandis is in early spring and early April, and the site preparation should be fine. After sowing, cover 0.5 cm of fine soil to keep the water co...

Abstract

The invention discloses a method for interplanting stipa grandis in an urban garden in a saline and alkaline area. The method comprises steps as follows: 1) selection of cultivation land: broad-leaved forest land in the saline and alkaline area at the altitude of 2-5 m is selected, and 20% of river sand is mixed in top soil; 2) stipa grandis seeds are sown in the early April in the spring, land preparation is performed carefully, the land is covered with fine soil at the thickness of 0.5 cm after sowing so that water in the soil is maintained to range from 30% to 40%, and mulch film covering for heat preservation and moisture maintenance is performed; 3) watering is performed once after seedlings emerge, the water content of the soil is maintained to range from 35% to 50%; 4) mulching films are removed when the daily average temperature reaches 15 DEG C in the late April and the early May , watering is performed once every month to keep the water content of the soil to range from 35% to 45%, and fertilizer is applied to mainly supplement phosphorus and potassium fertilizer; 5) harvesting is performed from the end July and the early August, and alternatively, fallen caryopses are harvested in the early November. With the adoption of the method, the growth time of stipa grandis can be prolonged remarkably, and a higher yield can still be obtained in the broad-leaved forest.

Description

technical field [0001] The invention relates to the field of grass planting, in particular to a method for interplanting Stipa grandis in urban gardens in saline-alkaline areas. Background technique [0002] Stipa grandis, a herbaceous plant of the genus Stipa in the Gramineae family. In typical grasslands in the temperate zone, Stipa grandis can be eaten by all kinds of livestock. The basal leaves are abundant and can be preserved relatively intact until winter and spring, which can provide a large amount of forage for livestock. It is mostly born on vast, flat undulating plateaus. The soil is generally thick loamy or sandy loamy typical chestnut soil and dark chestnut soil. Stipa grandis has certain adaptability to sandy soil, but it is not suitable for the growth of Stipa grandis on meadow soil or saline-alkali soil that is often affected by groundwater. Therefore, there are challenges in planting Stipa grandis in plain saline-alkali land. Contents of the invention ...
