Cultivation method of low-temperature pepper seedlings

Abstract

The invention provides a cultivation method of low-temperature pepper seedlings, and belongs to the technical field of seedling-growing production of overwintering peppers. The method comprises the following steps of A, selection of good varieties; B, seed soaking by an agent, wherein firstly, seeds are soaked by warm water at 45-50 DEG C, then soaked in clear water at normal temperature for 1.5-2.5 h, and then put in a 1% trisodium phosphate solution; C, temperature-varying germination accelerating; D, sowing in a seedling growing tray; E, seedbed management, wherein when it is sunny in the end of November and the pepper seedlings grow robustly, the seedling growing plug is lifted a little bit, so that roots are broken, 3-5 sunny days after root breaking should be ensured so that seedlingrecovery can be conducted, transplanting and field planting are conducted in a greenhouse when it is sunny after the Beginning of Spring, and transplanting and field planting are conducted in an openfield after a gale and around Fresh Green. According to the cultivation method, heeling in temporary planting is not needed, diseases can be reduced, the cultivated seedlings have a large germinationpotential and grow robustly, flower bud differentiation is early, and the seedlings cultivated by open-field transplanting and greenhouse field planting are put into the market 25 days and 50 days separately earlier than common peppers do.

Description

technical field [0001] The invention relates to a method for cultivating low-temperature pepper seedlings, in particular to a method for cultivating low-temperature pepper seedlings without artificial planting. Background technique [0002] Pepper is an important vegetable with high nutritional value, containing vitamin C, B, carotene, calcium, iron and so on. However, the normal open-field autumn stubble red peppers can only be harvested until late October, but through the technology of delaying autumn and overwintering in greenhouses, summer sowing, autumn planting, and winter harvesting can be realized, and the supply period of peppers will be changed from the original 10. It will be postponed from the end of March to December until April of the following year. But overwintering pepper seedlings is a technical problem. The sowing time is generally at the end of October, so the light is too strong, which is not conducive to the growth of pepper seedlings and seedlings, es...

AI Technical Summary

Problems solved by technology

But overwintering pepper seedlings is a technical problem. The sowing time is generally at the end of October, so the light is too strong, which is not conducive to the growth of pepper seedlings and seedlings, especially in December from the seedling stage to the adult plant stage, and the temperature is low in December. The temperature is often closed, so the humidity in the shed is high and there are many diseases

And it is planted in the soil, which increases the soil-borne diseases. If the cultivation management is slightly negligent, it is easy to induce the occurrence of virus damage, resulting in reduced production.

In the prior art, water-selected seeds only select unfulfilled seeds, and seeds with poor activity cannot be selected.

, Some of the selected seeds have weak seedling quality, are susceptible to diseases, and the composition of flower buds is slow. After transplanting, the survival rate is low, which is not conducive to high yield; The water retention capacity of the soil is poor, and the frequency of watering needs to be increased, which is time-consuming and labor-intensive, which is not conducive to seed growth, and is prone to soil-borne diseases

The existing technology of overwintering pepper seedlings needs to be artificially planted when the weather is fine in November to ensure that the seedlings are strong. Because the seedling period is long and the density of the seedlings is high, the quality of the seedlings cannot be guaranteed. The temperature is low, it is difficult to slow down the seedlings after artificial planting, the weather is bad, and the seedlings are not easy to survive the winter

However, in November, when the seedlings are small and are in the flower bud differentiation stage, the root system is delicate and fragile, and the damage is relatively large during the false planting. After the planting, there are many deformed fruits in the early stage and the yield is low. Wounds are easy to form on the stem, which affects the disease resistance of the seedlings, and the fine hairs on the stem inevitably fall off, resulting in a decrease in plant disease resistance and an increase in the possibility of disease occurrence
