Embodiment Construction

[0027] Below will describe the present invention's scheme design in detail by embodiment:

[0028] combined with figure 1 , the invention discloses a method for preserving seedlings of winter-planted potatoes in a high-temperature and humid climate environment along the southern coast. The method for preserving seedlings includes the following steps:

[0029] a. Soil preparation and ridging: spread the fertilizer on the ground before raising the ridge, and then raise a high ridge in the flat paddy field 1. Spread the fertilizer on the ground before raising the ridge, and fully mix the fertilizer and the soil during the ridge It can prevent potato seedlings from burning their roots;

[0030] b. Build a drainage system: excavate vertical and horizontal drainage ditches 2 between the high ridges, and excavate several reservoirs in the low-lying areas of the field, so that the water in the drainage ditches can flow into the reservoirs by itself, realizing the use of deep ditches...

Abstract

The invention discloses a method for protecting seedlings of potatoes planted in winter in the high-temperature humid climate on the coast of the southern area in China. According to the method, the seedlings of the potatoes planted in winter in the high-temperature humid climate of the coast of the southern area in China are protected and cultured through soil preparation and ridging, water drainage system building, grounded planting, seedling covering and watering for soil wetting. In the grounded planting operation process, potato seeds are laid on a ridge surface of a single ridge of double rows, seed coat and bud eyes are downward, a layer of fine soil is scattered on the ridge surface, and accordingly breathability can be improved due to a flat-laying and thinly-covering mode, the seedlings of the potatoes can quickly come out of the soil and grow quickly under the photosynthesis, and meanwhile, the seedlings are protected and cultured in a straw covering mode in the step of seedling covering, buds of the seedlings of the potatoes are thick and strong, potatoes bodies and roots of the potatoes do not rot, the seedlings grow well, the survival rate of the seedlings is high, and the method is ingenious, strong in practicability, and very suitable for universally popularized and used.

Description

technical field [0001] The invention relates to the potato planting seedling conservation and seedling raising technology in the high-temperature and high-humidity environment in the southern coastal area of ​​China, and the used technical method relates to the agricultural planting technology. Background technique [0002] According to the records of agricultural technical literature and actual planting experience, potatoes prefer cool climate conditions, and the suitable growth temperature is 16-18°C; no tuber formation will occur if it is higher than 25°C during the day or higher than 23°C at night; the large temperature difference between day and night is conducive to potato growth. The block swells; the daily sunshine hours are preferably 11-13 hours, and the plants grow luxuriantly and do not form tubers after more than 15 hours. The storage temperature of seed potatoes is 1-3°C. [0003] According to the growth and development characteristics of potatoes, most of th...
