Embodiment 1

[0024] 1. Select tomato seeds according to the standards that the seed clarity is higher than 98%, the seed color is pure, no mildew, the purity is higher than 95%, the germination rate is higher than 88%, and the moisture content is lower than 8%.

[0025] 2. Soak the tomato seeds in warm soup, specifically, including: soaking the tomato seeds in clear water for 2 hours; taking out the tomato seeds and putting them in hot water at 52°C, maintaining the water temperature for soaking the seeds for 15 minutes; and then continuing to soak the seeds for 3 hours under the condition of natural cooling of the water temperature ; then place the tomato seeds on gauze and filter out excess water.

[0026] 3. Select 50 hole trays according to the length of the root system of the tomato seedlings and the number of lateral roots, wherein the length of the 50 hole trays is 54cm, the width is 28cm, the height is 4cm, and the capacity is 50mL.

[0027] 4. According to parts by weight, weigh a...

Embodiment 2

[0034] Consistent with the tomato seedling raising method of Example 1, the difference is that in the different growth stages of tomato seedlings, dry Tenebrio molitor excrement is used according to the following concentrations:

[0035]When the tomato seedlings have 2 cotyledon leaves, apply insect manure according to the concentration of Tenebrio molitor manure: soil volume ratio of 1:200; when the tomato seedlings have 2 true leaves, according to the volume ratio of Tenebrio molitor manure: soil is Apply insect manure at a concentration of 1:100; when tomato seedlings have 4 true leaves, apply insect manure at a concentration of Tenebrio molitor manure: soil volume ratio of 1:100.

Embodiment 3

[0037] Consistent with the tomato seedling raising method of Example 1, the difference is that in the different growth stages of tomato seedlings, dry Tenebrio molitor excrement is used according to the following concentrations:

[0038] When the tomato seedlings have 2 cotyledon leaves, apply insect manure according to the volume ratio of Tenebrio molitor: soil at a concentration of 1:300; when the tomato seedlings have 2 true leaves, use Tenebrio molitor manure: the volume ratio of soil is Apply insect manure at a concentration of 1:200; when tomato seedlings have 4 true leaves, apply insect manure at a concentration of Tenebrio molitor manure: soil volume ratio of 1:200.

Abstract

The invention provides a tomato seedling raising method. The method includes the steps of soaking tomato seeds in warm water; according to the growth demands of the tomato seeds, selecting seedling raising plates; filling the seedling raising plates with nutrient soil, applying water to the soil, and keeping the nutrient soil wet; planting the tomato seeds in the seedling raising plates, and covering the tomato seeds with the nutrient soil; maintaining the nutrient soil wet, and after the tomato seeds germinate, applying water and frass different in amount at the different time periods; when tomato seedlings are 25-35 days old and every leaf center is surrounded by four leaves, conducting field planting on the tomato seedlings. By adopting the provided tomato seedling raising method, the germination rate of the tomato seeds is high, the seedling raising time is short, and more robust tomato seedlings can be obtained; the survival rate of the transplanted tomato seedlings is ensured; moreover, the frass of yellow mealworms is more environmentally friendly and free of smell compared with other fertilizer, and a novel approach is provided for seedling raising of the tomato seeds.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for growing tomato seedlings. Background technique [0002] Solanaceae plants are one of the plant groups with the greatest economic value, among which tomato is widely cultivated in the north and south of my country and has become an important economic crop in China. Tomato seeds have a long germination period (from sowing to the appearance of the first true leaf (broken heart). Under normal temperature conditions, this period is 7 to 10 days), and the seedling stage is when tomatoes grow excessively from vegetative growth to reproductive growth and vegetative growth The transition period of the same development can directly affect the formation of tomato product organs and yield. Well-cultivated tomato seedlings (thick stems with short internodes, thick and dark leaves, intact stems and leaves without pests, well-developed root system and white roots) can improve ...
