Embodiment 1

[0023] (1) Culture substrate preparation: crush straw (22.5 kg) and dry cow dung (22.5 kg), urea (0.3 kg), gypsum powder (0.5 kg), lime (0.45 kg), superphosphate (0.5 kg) Mix evenly, adjust the water content to 65%, put into plastic bags, 2kg per bag, and sterilize (121°C, 1 h);

[0024] (2) Inoculation: under sterile conditions, inoculate 0.5 portion of white rot fungi into the culture medium in the cultivation bag, tie the mouth, and culture in the dark (25°C, 2 weeks). After the culture medium is covered with hyphae, the culture medium Take it out from the plastic bag, crush it appropriately, it is the probiotics, and store it at 4°C;

Abstract

The invention relates to a microecological preparation for relieving continuous cropping problem of rehmannia and application of the microecological preparation. The microecological preparation comprises the following raw materials in parts by weight: 0.5-1 part of white rot fungi, 200-250 parts of straws, 200-250 parts of dry cow dung, 2-4 parts of urea, 4-6 parts of gypsum powder, 4-5 parts of lime and 4-6 parts of calcium superphosphate. The microecological preparation is prepared through the steps of inoculating a strain into a culture medium in a culture bag under an aseptic condition, sealing, and culturing in a dark place; and after mycelia grow on the culture medium, taking out the culture medium from the plastic bag, and smashing to obtain the microecological preparation. By using the microecological preparation, the continuous cropping problem problems such as serious diseases and yield reduction of continuously-cropped rehmannia can be effectively solved.

Description

technical field [0001] The invention relates to the field of cultivation of Rehmannia glutinosa, in particular to a microecological preparation for alleviating obstacles to rehmannia rhizome cultivation and application thereof. Background technique [0002] Rehmannia glutinosa ( Rehmannia glutinosa Libosch) is a perennial herb of Scrophulariaceae. It is one of the famous "four bosom medicines" in my country. It has a long history of medication and definite clinical curative effect. The planting area in Jiaozuo area of ​​Henan Province (the real estate area) has reached nearly 15,000 hectares, and the output value has reached several billion yuan. [0003] Continuous cropping obstacle refers to the phenomenon that after continuous cropping of the same crop or related crops, even under normal management conditions, the yield will be reduced, the quality will be deteriorated, and the growth status will be deteriorated. During the planting process of Rehmannia glutinosa, there...
