Embodiment 1

[0029] Example 1 Production of earthworm feces, the main raw material of watermelon seedling raising substrate:

[0030] 1. Production of earthworm manure, the main raw material of watermelon seedling substrate

[0031] (1) Earthworm base material preparation: The traditional Chinese medicine residue used is the residue after the active ingredients are extracted from the mixture of Achyranthes bidentata, honeysuckle, dendrobium, and Scrophulariaceae. Fresh and wet Chinese medicine residue (water content 70-80%), straw (water content 15 ~25%) After coarsely pulverizing, weigh 80% of traditional Chinese medicine residue and 20% of rice straw on the basis of dry matter, and mix well, adjust the water content to 60~70%, and the C / N ratio is 25~40 , PH7~7.5, access to BGB biological agent 5kg / m 3 After fermentation, the base material of earthworms is made. The fermentation process when making the base material is as follows: the fermentation temperature reaches 55-65°C, lasts for 5-7 d...

Embodiment 2

[0043] Example 2 Screening and preparation of watermelon seedling substrate

[0044] 1. Screening of the ratio of vermicompost, vermiculite and perlite

[0045] According to the requirements of watermelon seedlings for the physical and chemical properties of the substrate (bulk density 0.2~0.4g / cm 3 The total porosity is 60%~80%, the macropores are 20~25%, the pH should be neutral and acidic, and the nutrient concentration should be moderate (EC value 1.5~2.0ms / cm). We use the vermicompost produced in Example 1 as the main material , Vermiculite and perlite as auxiliary materials, within the dosage range of vermicompost: vermiculite: perlite with a volume ratio of 1~5:0.6:0.4, 5 formulas are combined according to different ratios (volume ratio) to The seedling substrate of agricultural watermelon was used as the control, with 6 treatments in total:

[0046] Formula 1: Vermicompost: Vermiculite: Perlite is 1:0.6:0.4;

[0047] Formula 2: Vermicompost: Vermiculite: Perlite is 2: 0.6: 0....

Embodiment 3

[0075] Example 3 Application effect test of the seedling raising substrate of the present invention

[0076] 1. The influence of the substrate of the present invention on the quality of watermelon seedlings

[0077] The test has 3 treatments:

[0078] Treatment 1: Huainong watermelon seedling nursery substrate was poured with nutrient solution (CK1); the nutrient solution formula was (in weight percentage): 0.1% urea, 0.1% potassium dihydrogen phosphate, and the balance was water. Water with the nutrient solution 15 days after seedling, and then water once every 10 days for a total of two times. When pouring the nutrient solution, the substrate should not be too dry, and the amount of irrigation should be half of the usual amount of irrigation each time.

[0079] Treatment 2: The nutrient solution (CK2) is not poured on the seedling substrate of Huainong watermelon;

[0080] Treatment 3: The substrate of the present invention is not poured with nutrient solution. The substrate is prep...

Abstract

The invention belongs to the technical field of agriculture and discloses a watermelon seedling culturing substrate, which comprises the following components: earthworm cast, vermiculite, pearlstone and paclobutrazol, wherein the volume ratio of the earthworm cast to the vermiculite to the pearlstone is (2-3):0.6:0.4; and the dosage of the paclobutrazol is between 10 g/m<3> and 20 g/m<3>. When the substrate is used for culturing watermelon own-rooted seedlings, a nutrient solution does not need to be replenished, the seedlings are in order and strong without growing excessively, and the root systems are developed. After the substrate is planted into soil along with the seedlings, beneficial microorganisms in the substrate can quickly form a dominant microflora around the rooting zone of a crop, so that nutrition elements in the soil can be activated, and the utilization ratio of a fertilizer is increased; the application amount of an inorganic fertilizer can be reduced by 20-30 percent; soil-borne diseases can be resisted effectively, the incidence rate of field blight is low, and the control effect is between 86.74 percent and 89.4 percent, is higher than the control effect of an efficient bactericide for an own-rooted seedling growing from the ordinary substrate, and is basically close to the control effect of a grafted seedling; and the soluble sugar content of watermelon and the yield are increased.

Description

Technical field [0001] The invention belongs to the field of agriculture, and specifically relates to a watermelon seedling raising substrate and its application. Background technique [0002] Watermelon is rich in nutrients and high in water content. It ranks first in the natural nutrient juice content of all fruits. It is called "the king of summer melons and fruits". It has become a favorite for people to cool off and is widely cultivated throughout the country. In watermelon cultivation, watermelon seedling cultivation is a necessary measure to shorten the growth time of watermelon in the field, reasonably adjust the crop, save land, labor, and time, and achieve early maturity and high yield. Traditional watermelon seedlings are grown in soil nutrient bowls, but with the development of seedling technology, light-substrate plug seedling technology has been widely used. The light-substrate materials used are mainly grass charcoal, edible fungus chaff, vegetable plant residues, ...
