Seedling cultivation method for promoting crop seedling stem growth

Abstract

The invention provides a seedling cultivation method for promoting growth of crop seedling stems, and relates to the technical field of green pepper seedling culture, in the first stage from germination to growth of two leaves and one core of a seedling, high temperature and humidity are controlled, and the germination rate of seeds is guaranteed; in the second stage from two-leaf and one-core growth of the seedling to two days before transplanting (the seedling can be transplanted after five-leaf and one-core growth of the seedling), the temperature and the humidity are reduced, the watering frequency is reduced, the root of the seedling can breathe and branch in the wheat straw layer and grow downwards as much as possible, and therefore the root of the seedling is developed, and the survival rate of the seedling is increased.

Description

Technical Field

[0001] The invention relates to the technical field of green pepper seedling cultivation, in particular to a seedling cultivation method for promoting the growth of crop seedling stems. Background Art

[0002] Chili pepper is a variety of pepper of the genus Capsicum in the Solanaceae family. It has a wide planting area in my country and is the second largest vegetable crop in my country. Pepper seedlings are an important foundation for high-quality, high-yield and stable yields of pepper. Taking the stems of peppers as the statistical basis, it is found that the thicker and more shaped the stems of the green pepper seedlings, the greater the yield of green peppers and the longer the fruiting period.

[0003] The thickness of the green pepper stem is directly related to the root system. For pepper seedlings that have root rot and root burn during seedling cultivation and planting, their stems will not be very thick no matter how they are cultivated in the later stage, and the yield will decline. Therefore, how to promote the growth of the stems during the green pepper seedling stage is the key to increasing the yield of green pepper and extending the fruiting period. To this end, the present invention provides a seedling cultivation method for promoting the growth of the stems of crop seedlings. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a seedling cultivation method for promoting the growth of crop seedling stems, which solves the problem of promoting stem growth during the green pepper seedling stage, increasing the green pepper yield and prolonging the fruiting period.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A seedling cultivation method for promoting the growth of crop seedling stems comprises the following steps:

[0007] Seedling medium: Spread the first soil layer in the seedling cultivation box, the thickness of the first soil layer is 5cm-10cm, then spread the wheat straw layer on the first soil layer, the thickness of the wheat straw layer is less than 1cm, then spread the second soil layer on the wheat straw layer, the thickness of the second soil layer is 2-3cm, and finally water it completely;

[0008] Sowing: Soak the seeds in 30℃-35℃ water for 15-30 minutes, then transfer to 10% trisodium phosphate solution and soak for 5 minutes. After washing the residue on the surface of the seeds with water, sprinkle them evenly on the second soil layer and cover them with a layer of black soil less than 1cm thick.

[0009] The first stage: The seedlings are in the first stage from germination to the growth of two leaves and one core. During the first stage, the temperature is controlled at 24℃-27℃, the humidity is 70%-75%, and the humidity is 40-45ml / dm 2 Water every day with the amount of water;

[0010] The second stage: The second stage is from the time when the seedlings grow two leaves and one core to 2 days before transplanting. During the second stage, the temperature is controlled at 20℃-22℃, the humidity is 40%-50%, and the humidity is controlled at 30-50ml / dm 2 Water every other day;

[0011] The temperature was controlled at 20℃-22℃ and humidity at 70%-75% for 2 days before transplanting. 2 Water every day.

[0012] Preferably, the first soil layer and the second soil layer are both formed by mixing 5%-10% peat, 5%-10% perlite and the remainder black soil.

[0013] Preferably, the first soil layer and the second soil layer are both made of compost.

[0014] Preferably, the water used in the first stage and the second stage is fertilizer water mixed with 8% by mass of compound fertilizer.

[0015] Preferably, the water used in the second stage contains 10g-20g of seaweed fertilizer or chitin rooting fertilizer per 1L of water.

[0016] Preferably, ventilation openings are reserved at the four sides of the wheat straw layer.

[0017] Preferably, transplanting is performed 1-2 weeks after the seedlings have 5 leaves and 1 heart.

[0018] Preferably, on the day after transplanting, water the plants once with a mixture of 0.3% urea and 0.1% potassium dihydrogen phosphate, and then water them again with clean water 2 hours later.

[0019] The present invention provides a seedling cultivation method for promoting the growth of crop seedling stems. The method has the following beneficial effects:

[0020] 1. The present invention controls relatively high temperature and humidity in the first stage from the germination of seedlings to the growth of two leaves and one core to ensure the germination rate of seeds, and lowers the temperature and humidity and reduces the number of watering times in the second stage from the growth of two leaves and one core to 2 days before transplanting (seedlings can be transplanted after they grow 5 leaves and one core), so that the roots of the seedlings can breathe and fork in the wheat straw layer and grow downward as much as possible, thereby making the roots of the seedlings more developed and able to absorb sufficient nutrients from the soil after transplanting, making the stems of the green pepper seedlings more sturdy, increasing the yield of the green pepper and extending the fruiting period.

[0021] 2. The present invention adopts a three-layer structure consisting of a first soil layer, a wheat straw layer, and a second soil layer. The wheat straw layer can provide better ventilation for the root system, thereby avoiding root rot and root burn. In addition, the root system is not tightly connected to the soil at the wheat straw layer, so root breakage is not likely to occur during transplanting, thereby improving the survival rate of seedlings.
