Method for breeding bulbs of bulbus lilii by aid of sunlight greenhouses

Abstract

The invention discloses a method for breeding bulbs of bulbus lilii by the aid of sunlight greenhouses. The method has the advantages that cutting is carried out in early April at the end of spring and the beginning of summer, the temperature difference between the indoor temperature and the temperature required by cutting is low, and accordingly the method is favorable for saving electric power; the bulbs are bred in the sunlight greenhouses, are planted in autumn and winter and are harvested in summer, accordingly, the high temperatures in the summer can be avoided, growth conditions of the bulbus lilii can be met, and the method is favorable for promoting growth of the bulbus lilii; the bulbs with high quality can be produced; growth periods of aboveground parts of the bulbus lilii can be prolonged owing to appropriate growth environments, nutrient accumulation can be promoted, and accordingly the method is favorable for expansion of lower parts of the bulbus lilii; flower bulbs of underground parts of the bulbus lilii have neat sizes and are larger than bulbs obtained by means of conventional breeding; the bulbs are cultivated by the aid of rain sheltering and insect-proof nets, accordingly, the bulbus lilii rarely suffers from plant diseases and insect pests, the usage of pesticides can be reduced, the production cost can be lowered, and environmental pollution due to the pesticides can be abated; the growth periods of the bulbus lilii are in non-high-temperature seasons, the insect-proof nets cover the bulbus lilii, yellow sticky boards are suspended, accordingly, emergence of phloem-sucking pests can be reduced, and virus disease propagation can be prevented.

Description

Technical field [0001] The invention relates to a lily bulb breeding technology, in particular to a method for breeding lily bulbs in a solar greenhouse. Background technique [0002] The conventional method is cutting at the end of September and early October, and planting in early and mid-February of the following year. The disadvantages: 1. High temperature can cause premature senescence of the above-ground part of the lily, shorten the growth period of the lily, and is not conducive to the expansion of the underground part. 2. In summer, lily diseases are severe and difficult to control, and blight, anthracnose, gray mold, etc. are easy to occur, causing the above-ground parts to die. 3. With high summer temperature and high ground temperature, lily wilt is easy to occur, causing lily bulbs to rot. 4. In summer, piercing and sucking pests such as aphids, thrips, and whiteflies are severely harmful, leading to mutual transmission of viral diseases. 5. The harvested bulbs are...

AI Technical Summary

Problems solved by technology

[0002] The conventional method is to cut the cuttings at the end of September and the beginning of October, and plant them in the first and middle days of February of the next year. The disadvantages: 1. High temperature time will cause the premature aging of the lily aboveground, shorten the growth period of the lily, and is not conducive to the expansion of the underground part

2. In summer, lily diseases are serious and difficult to control. Blight, anthracnose, gray mold, etc. are prone to occur, causing the above-ground parts to die

3. In summer, the temperature is high and the ground temperature is also high. Lily wilt is very easy to occur, causing lily bulbs to rot

4. In summer, aphids, thrips, whitefly and other piercing-sucking pests do serious harm, causing mutual transmission of viral diseases

5. The harvested bulbs are uneven in size and the number of harvested is small
