Rotation cropping mode of oriental lilies for cut flowers and alfalfa

Abstract

The invention discloses a rotation cropping mode of oriental lilies for cut flowers and alfalfa. In a solar greenhouse, the rotation cropping mode includes lily cultivation from August of the first year to February of the second year and alfalfa cultivation from March to June of the second year. The lily cultivation includes the following steps: (1) preparing soil and performing fertilizing for bedding; (2) performing watering and performing shading; (3) planting terminal buds of lily seed ball bulbs upwards; (4) performing watering completely after planting and maintaining moisture, nutrition, illumination, temperature and humidity; (5) performing harvesting when lily buds is coloring; and (6) preparing the soil of crops for rotation for later use. The alfalfa cultivation includes the following steps: (7) preparing soil for bedding; (8) performing broadcast sowing or strip sowing; (9) performing watering completely after sowing, maintaining moisture and nutrition and performing intertillage weeding; and (10) chopping the roots and stems of sickle alfalfa in a field, performing ploughing up and returning to the field, performing irrigation for 10cm-15cm, performing waterlogging for30d-40d and preparing to plant next-stubble lilies. The mode provided by the invention can improve the physical and chemical conditions of soil in a greenhouse and facilitate the production of good-quality lilies for the cut flowers.

Description

technical field [0001] The invention belongs to the technical field of crop rotation cultivation, and in particular relates to a crop rotation cultivation pattern of cut flowers oriental lily and alfalfa under the condition of a solar greenhouse. Background technique [0002] The use of solar greenhouses for crop cultivation is not only efficient but also annual production is the main means and needs of modern high-efficiency agriculture and material civilization. However, the development of a solar greenhouse requires a large investment. Once it is built, it can only be planted in the same place year after year. At the same time, due to its immobility and the high temperature and high humidity environment in the greenhouse, problems such as soil degradation are becoming more and more serious, resulting in an increase in pests and diseases. , The growth of plants is weak and the quality is declining. Flower farmers can only choose to rebuild facilities in different places or...

Problems solved by technology

However, the development of a solar greenhouse requires a large investment. Once it is built, it can only be planted in the same place year after year. At the same time, due to its immobility and the high temperature and high humidity environment in the greenhouse, problems such as soil degradation are becoming more and more serious, resulting in an increase in pests and diseases. , the growth potential of plants is weak, and the quality declines. Flower farmers can only choose to rebuild facilities in different places or choose other industries. This not only increases investment but also affects farmers' enthusiasm for production, and seriously restricts the development of high-efficiency facility industries.

[0003] The conventional crop rotation mode of solar greenhouses in cut flower production areas is mainly a single "flower + flower" or "flower + vegetable" planting mode. Farmers simply arrange crops blindly based on their own habits and markets, and do not pay attention to crop rotation and soil fertilization and improvement. , which aggravates the soil continuous cropping obstacles and degradation in solar greenhouses to varying degrees

Disadvantages of the conventional crop rotation mode: (1) The soil in the greenhouse is seriously degraded, with poor physical and chemical properties, which is not conducive to plant growth; (2) Long-term continuous cropping, serious production obstacles and serious pests and diseases, the quality of cut lily products is low, the flower buds are easily aborted, and the flower diameter is small , thin stems, etc.
