Problems solved by technology

[0003] At present, most rice seedlings are still raised with nutrient soil. Most of the nutrient soil is self-made by the growers. The preparation of nutrient soil is cumbersome and labor-intensive. It does not meet the requirements of factory production and it is difficult to achieve industrialization. To a certain extent Restricted the development of machine-transplanted rice seedlings
However, there are few researches and patents about the light-duty seedling-raising substrate, and the seedling-raising substrate made of fungus residue as the main raw material has not yet been announced. The main raw materials such as peat are prepared by adding certain water-retaining agents and binders and other auxiliary materials. For example, the patent CN107032909A discloses a rice seedling raising substrate and its production method. The weight percentage of the raw materials is: livestock and poultry manure 30%-35% , 10%-15% of crop straw, 5%-10% of camellia cake, 4%-6% of bran husk, 10%-15% of agricultural product processing waste, 0.02%-0.1% of organic fertilizer decomposing agent, and 5% of vermiculite -6%, dry fine soil 10%-15%, regulator 0.4%-0.6%; but there are still problems such as complex process, high cost, difficulty in obtaining raw materials, unstable quality, and poor water retention

Embodiment 1

[0016] A special seedling-raising substrate for machine-transplanted medium and large seedlings of hybrid indica rice, including main materials and auxiliary materials. The main materials include 90% of decomposed fungus residue and 10% of dry fine soil;

[0017] Auxiliary materials include urea, superphosphate, uniconazole, carbendazim and dexazone, and the weight ratio of the main material to urea is 2000:3, and the weight ratio of the main material to superphosphate is 400:3. The weight ratio to uniconazole is 4×10 6 :3, the main ingredient and carbendazim weight ratio are 4000:1, and the main ingredient and dexon weight ratio are 4000:1.

[0018] A method for preparing a special seedling-raising substrate for machine-transplanting medium and large seedlings of hybrid indica rice, the steps comprising:

[0019] (1) Bacteria residue pretreatment: remove hard impurities, control the moisture content of the bacteria residue to be controlled at 35-45%;

[0020] (2) Fermentati...

Embodiment 2

[0024] A rice substrate seedling cultivation method, comprising:

[0025] (1) The matrix that the present invention cooperates has invented the medium-large seedling seedling wet-oxygen cultivation method, and the medium-large seedling wet-oxygen cultivation method can effectively improve the quality of planting (as shown in Table 2), and can increase the elasticity of the seedling age (Table 1).

[0026] Substrate seedling raising method steps are as follows:

[0027] Step 1: Choose a fertile and flat seedling field to make a moisturizing seedling box with a width of 1.1-1.4 meters, and ditch around it to facilitate irrigation and drainage;

[0028] Step 2: Start soaking the seeds one day before sowing, soak the seeds for more than 12 hours, and then dry them until the seeds are loose and not sticky;

[0029] Step 3: Use the fully automatic rice seedling raising and sowing line to complete the steps of substrate laying, sowing and covering;

[0030] Step 4: Place the sown s...

Abstract

The invention relates to the field of technologies for planting rice, in particular to a method for preparing a special rice seedling raising medium for mechanically transplanting medium and large seedlings of hybrid non-glutinous rice and application of the special rice seedling raising medium. The special rice seedling raising medium comprises main materials and auxiliary materials. The main materials include 90% of thoroughly decomposed mushroom dreg and 10% of dry fine soil; the auxiliary materials include urea, calcium superphosphate, uniconazole, carbendazim and dexon, a weight ratio ofthe main materials to the urea is 2000:3, a weight ratio of the main materials to the calcium superphosphate is 400:3, a weight ratio of the main materials to the uniconazole is 4*10<6>:3, a weight ratio of the main materials to the carbendazim is 4000:1, and a weight ratio of the main materials to the dexon is 4000:1. The method and the application have the advantages that organic raw materials for the special rice seedling raising medium are thoroughly decomposed by the aid of biological thorough decomposition technologies at the high temperatures, and accordingly sterilization and disinfection effects can be realized; the carbendazim, the dexon and the like for sterilizing and disinfecting the organic raw materials are further added into the organic raw materials after the organic raw materials are thoroughly decomposed, accordingly, damping-off of the seedlings can be effectively reduced when the seedlings are raised, and the seedling age elasticity of the seedlings can be improvedby the added uniconazole.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for preparing a special seedling-raising substrate for machine-transplanting medium and large seedlings of hybrid indica rice and its application. Background technique [0002] Rice is one of the three major food crops in my country, with a planting area of ​​28-30 million ha 2 Right and left, rice production plays a pivotal role in ensuring food security. In recent years, mechanization has been applied to all aspects of rice production, and mechanized farming, transplanting and harvesting have developed rapidly across the country. However, mechanized rice planting is still a relatively weak link compared to plowing and harvesting. The main reason is that the seedling raising technology does not perfectly match the mechanized transplanting technology. Seedling raising technology is an important supporting technology for machine transplanting, and the most importa...
