The Method of Raising Overwintering Pepper Seedlings Without Artificial Planting

Abstract

The invention discloses an over-wintering pepper seedling cultivating method without need of heel-in, and belongs to the technical field of over-wintering pepper seedling cultivating and producing. The method includes the following steps that A, good seeds are selected; B, the seeds are soaked in medicament, wherein the seeds are socked in warm water with the temperature of 50-55 DEG C, then is soaked in normal-temperature clean water for 2+ / -0.5 hours and are placed in a 1% trisodium phosphate; C, the temperature is changed to accelerate germination; D, the seeds are sown in a seedling growing hole tray; E, seedbed management is carried out, wherein when it is sunny at the end of November and pepper seedlings grow vigorously, the seedling growing hole tray is tilted once so that roots can be cut, it is guaranteed that it is sunny for 3-5 days after root cutting for rejuvenation, the seedlings are transplanted and planted in a greenhouse on sunny days after the beginning of spring, and the seedlings are transplanted and planted in open fields after windy days around the tomb-sweeping day. According to the method, heel-in is not needed, disease disasters can be reduced, the cultivated pepper seedlings sprout strongly and grow strongly, flower bud differentiation is early, and compared with common peppers, transplanting in the open fields and planting in the greenhouse of the pepper seedlings are 25 days earlier and 50 days earlier in the market.

Description

technical field [0001] The invention relates to a method for raising overwintering pepper seedlings, in particular to a method for raising overwintering 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, especially in ...

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
