Capsicum annuum seedling cultivating method

Abstract

The invention discloses a capsicum annuum seedling cultivating method which comprises the following steps: 1) planting strawberry and capsicum annuum seedlings alternatively every three years in a greenhouse, preparing soil as a capsicum annuum seedling bed, breeding chicken, ducks and / or geese in the soil preparation alternative dormancy period, so as to obtain a base fertilizer; 2) selecting capsicum annuum seeds which are good in cold resistance and plant type; 3) seeding in the seedling bed; 4) after emergence of seedlings, controlling the day temperature to be about 20-22 DEG C and the night temperature to be 16-18 DEG C; 5) after the seedlings are 3-4cm height and have 2-3 main leaves, controlling the day temperature to be about 22-25 DEG C and the night temperature to be 15-18 DEG C. By adopting the capsicum annuum seedling cultivating method, strawberry and capsicum annuum are planted alternatively in the greenhouse every three years, chicken, and ducks and / or geese are bred in the soil preparation alternative dormancy period, so that uniform soil fertility can be ensured, soil porosity can be increased, ventilation and water retention property of soil can be improved, and by controlling the temperature, water and light, constitution of capsicum annuum seedlings can be improved, the damping-off disease of the capsicum annuum seedlings is reduced, and the survival rate of the capsicum annuum seedlings is increased.

Description

technical field [0001] The invention belongs to the technical field of horticulture and vegetable cultivation, and in particular relates to a seedling raising method for pepper seedlings. Background technique [0002] Pepper is a warm-loving plant, and it has high requirements for temperature adaptation. The temperature range of pepper growth cycle is 12-35°C, and the survival rate of pepper seedlings below 12°C or above 35°C is relatively low. Most of them are planted in the open air or in seedbeds. When the weather temperature in the seedling stage of pepper seedlings or the temperature in the seedbed is low, pepper seedlings are prone to damping-off disease. Due to the poor control of the planting temperature in the open air or in the seedbed, the pepper seedlings will experience falling flowers, Falling fruit and leaves cause pollen infertility, leading to failure of normal fertilization, leading to flower drop and fruit drop, resulting in low yield of pepper.

[0002] Pepper is a warm-loving plant, and it has high requirements for temperature adaptation. The temperature range of pepper growth cycle is 12-35°C, and the survival rate of pepper seedlings below 12°C or above 35°C is relatively low. Most of them are planted in the open air or in seedbeds. When the weather temperature in the seedling stage of pepper seedlings or the temperature in the seedbed is low, pepper seedlings are prone to damping-off disease. Due to the poor control of the planting temperature in the open air or in the seedbed, the pepper seedlings will experience falling flowers, Falling fruit and leaves cause pollen infertility, leading to failure of normal fertilization, leading to flower drop and fruit drop, resulting in low yield of pepper. In addition, another important indicator of pepper growth is water. Too much water in the soil is prone to hypoxia, resulting in reduced or damaged root vitality. The absorption capacity of the roots of pepper seedlings decreases, and the long-term water shortage and drought in the soil cause uncoordinated water supply of the plants. Due to the limitations of the western region, long-term low temperature, rainy and foggy days, the existing open-air or seedbed planting will lead to insufficient light, long-term low temperature, rainy and foggy If the planting density is too high, the distance between rows and rows of plants is unreasonable, and the plant growth will be too weak if the light is insufficient. If the air density is too high, the pollen will absorb water and swell, and cannot be scattered from the anthers, which will affect pollination and fertilization. Pepper seedlings produce various diseases and insect pests, such as "aphids, whiteflies and tea yellow mites, etc.
