Abstract
This invention belongs to the super rice cultivation field, and discloses a
super-high-yield cultivating method for double-cropping super rice: select the
planting fields, and then plough and sterilize them; sprinkle lime and special manure
to the fields; confirm the variety to cultivate the seedlings; steep the fields and apply
base fertilizer; ensure the water is sufficient to grow the rice after transplanting; apply
herbicide fertilizer; keep the humidity at the tillering stage, and implement shallow
irrigation at the young spike formation and the flowering stage. For seedling, the
seeds are first soaked in dilute brine, and then soaked in germicide to kill the bacteria
and mould. Lastly, the seedlings are cultivated in the potting soil sprayed with
germicides to create a good environment for the rice to increase the germination
percent. This invention provides a light cultivation technique with simple operation
and precise fertilization to replace traditional cultivation process.

Description
Technical Field
The invention belongs to the field of super rice cultivation and particularly it relates to a super-high-yield cultivation method of double-cropping super rice.
Background
Rice belongs to herbaceous rice genus and is a cereal grain, which is the main and longest food comparing other species in the rice genus. According to morphological characteristics, cultivating seasons and the composition of endosperm starch, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, nonglutinous rice and glutinous rice respectively. Rice is the staple food for one-third of the world's human population. However, there are several problems in the current rice cultivating process, such as frequently applying fertiliser and medication, various rice species, complicated operating processes, high labouring and costing, which increase the difficulty for farmers to cultivate. Meanwhile, bacteria are easily grown during the seedling process which may affect the germination rate of rice seeds; also, water demand is large and therefore root rot and waste of water are prone to occur.
Invention Content
To fix existing technical problems, this invention provides a super-high-yield cultivation method for double-cropping super rice. The processes are listed as follows:
Step 1: select the planting fields with convenient irrigation and pollution-free, and then plough and sterilize them Step 2: sprinkle lime and special farm manure to the fields Step 3: confirm the double-cropping rice variety to cultivate the rice seedlings Step 4: operate the rice transplanter to transplant seedlings with the best density of 18,750 holes per mu on a cloudy day or a sunny afternoon Step 5: ensure the water is sufficient to for the seedlings to grow after transplanting, and then apply herbicide fertilizer after 5-7 days Step 6: keep the humidity at the tillering stage to ensure sufficient oxygen in the roots, and timely dry the field to control invalid tillers; implement shallow irrigation at the young spike formation and the flowering stage; harvest by machinery when the rice
Description
spikes are hanging down
Further, in the step 1, the ploughing depth is 20-24 cm. Further, in the step 2, the special farm manure consists of 100 to 300 portions of pig manure, 60 to 200 portions of poultry manure, 80 to 160 portions of straw, 50 to 130 portions of plant ash, 70 to 90 portions of fermented bacteria powder, 50 to 70 portions of husks, and 30 to 90 portions of dead branches and weeds. Further, in the step 2, the preparation method of special farm manure is:
(1) apply ethanol in the fermenting pool to disinfect pig manure and poultry manure (2) chop straw, dead branches and weeds (3) add the chopped straw, dead branches and weeds to the fermenting pool (4) sprinkle plant ash and fermented bacteria powder to the fermenting pool in sequence for fermentation for 3 to 4 weeks.
Further, in the step 3, the method of cultivating rice seedlings is:
(1) prepare the potting soil, and then spread them in the seedling plate (2) spray germicide on the surface of the potting soil until the moisture content achieve 45% (3) soak the seeds in brine with a mass fraction of 1.0%-1.2% for 3-4 hours, and then soak them in a germicide for 1.0 to 1.5 hours (4) drain the surface of seeds, and then rinse with water. After that, soak the seeds in glycerine for 1.0-1.6min, and then take it out (5) sown the seeds with glycerine on the surface in potting soil, and then spray water to achieve the soil moisture content of 79% to obtain the seedlings
Further, in the step 3, the potting soil is composed of 15 to 55 portions of potassium chloride, 35 to 55 portions of oyster shell powder, 150 to 250 portions of organic fertilizer, 20 to 40 portions of zeolite powder, 36 to 56 portions of vermiculite, 30 to portions of fine river sand, 8 to 16 portions of selenium fertilizer, 20 to 40 portions of calcium superphosphate, and 30 to 50 portions of ammonium sulphate. Further, in the step 3, the germicide is composed of 4 to 8 portions of lysozyme, 5 to 9 portions of lywallzyme, and 15 to 25 portions of 240 times wood vinegar, and 14 to 18 portions of 260 times 50% carbendazim wettable powder. Further, in the step 4, according to the target yield of about 800 kg per mu, the method of applying base fertilizer comprises:
Description
(1) A wide-adaptive super rice variety requires 12 kg of N element, 5 kg of P element, 12 kg of K element, and 8 kg of medium-micronutrient per mu, which shall be applied at one time when the field is raked; (2) A multi-spike super rice variety requires 10 kg of N elements, 7 kg of P elements, kg of K elements, and 10 kg of medium-micronutrient per mu, which shall be applied at one time when the field is raked; (3) A large-spike super rice variety requires 13 kg of N elements, 7 kg of P elements, 14 kg of K elements, and 12 kg of medium-micronutrient per mu, which shall be applied at one time when the field is raked.
Further, in step 5, weeding fertiliser controls and removes annual weeds; Pesticide controls chilo suppressalis, cnaphalocrocis medinalis and plant-hoppers; Germicide controls magnaporthe grisea and rhizoctonia solani. Further, in the step 1, when ploughing and sterilising the fields, raking and keeping the humidity of the soil should be immediately followed after ploughing. Soil should be sealed afterwards by evenly spraying 50% Trifluralin Emulsifiable Concentrates and 98% S-metolachlor diluting with water. After the spray, the soil should be shallow harrowed and blended, leaving in a pre-sowing condition.
There are advantages and positive effects of the novelty method:
The multi-component fertiliser and special weeding pesticide sterilising fertiliser applied in the fertilising method adopt advanced technology. Nutrients in fertiliser and effective ingredients in pesticides can be secured around the rice root system so that rice roots can absorb those according to its own needs and also the lasting period is long, which achieve the goal of providing fertiliser and medicine accurately avoiding the tradition way of three times of fertilising and three times of applying medicine (tillering fertiliser, booting fertiliser, seed-enhancing fertiliser, tillering stage, round-stem stage and grouting stage eliminating bacteria and other common diseases). This precise and simple cultivating method for super rice can not only realise providing fertiliser and medicine accurately by experts, but also easy for farmers to operate; Meanwhile, according to this rice seedling cultivating method, spraying germicide on the surface of potting soil can increase the sterilisation effect of Carbendazim, which provides a good environment for the growth of rice; Rice seeds are soaked in dilute brine at first and then they are soaked in germicide to completely kill bacteria, fungus and viruses carried by the seeds, which improves the germination rate and bud enhancing rate.
Description
Spreading lime and manure according to the method are beneficial for balancing the acidity and alkalinity of the soil, enriching the nutrients and facilitating growth, therefore, increasing the yield. After spraying water on potting soil in the seedling plates, excessive water from the potting soil flows out after being filtered by the filling layer, which keeps the rice in a relatively humid environment with reduced water usage and also avoids root rot condition so that increasing the yield.
In the process of ploughing and sterilising the rice fields, raking and keeping the humidity of the soil should be immediately followed after ploughing. Soil should be sealed afterwards by evenly spraying 50% Trifluralin Emulsifiable Concentrates and 98% S-metolachlor diluting with water. After the spray, the soil should be shallow harrowed and blended, leaving in a pre-sowing condition. It can effectively kill harmful bacteria and provide guarantee for rice cultivation.
