The Key Techniques of Rice Seedlings for Mechanical Transplanting

Rice mechanization transplanting is a most direct and efficient light and simple cultivation method. In recent years, the technology for large-scale application of rice mechanization transplanting has matured, and seedling raising technology is one of the key technologies for machine insertion. Now the following technical measures are provided for reference.

1. Requirements for Transplanters for Seedlings The specifications of the plutonium blocks required for walk-in or high-speed stand-type rice transplanters are 58.0 cm (28.0 cm) and 2.0 to 2.5 cm (length, width, height). Square corners are vertically squared with no missing edges. 1 to 2 seedlings per square centimeter, seedling height 10.0 to 20.0 centimeters, seedlings neatly and evenly, roots knotted, lifted up, can be put into the carton as a whole.

2. Ways of commonly used childbearing methods The methods of computerized childbearing that have been developed in recent years include hard disk breeding, floppy disk breeding, double film breeding, and other methods of childbirth. Hard disk breeding costs are higher, so it is appropriate to use floppy disk breeding and double film breeding methods. No matter what kind of rearing methods, dry and wet seedlings can be used. Dry seedlings are easy to control seedling height, with developed root system, good compaction, good flexibility, and short seedling period after transplanting, which is more conducive to high yield.

3. Determination of the sowing date The sowing date should be determined by taking into account the weather conditions of the estuary, grazing age, species, and local conditions. The age of the machine transplanter that is compatible with the wheat cornice is generally within 25 days. Therefore, the sowing time of winter free field and early indica rice field is consistent with the local hand transplanting, and it is planted in advance in the suitable planting period. The wheat (oil) farmland should be sown on the basis of the previous harvest time by 25 days.

4. Determination of seeding rate The seeding rate is mainly determined by the mechanical harvesting requirements and seedling quality. In the case of satisfying catching, the lower the unit area sowing, the higher the seedling quality. According to the number of seedlings per square centimeter, 1-2 seedlings, with an average of 1.5 seedlings, each seeding pan (58 cm 28 cm) requires 80-90 g sowing. The lower the 1000-grain weight, the smaller the seeding amount.

5. Mechanical plug in dry seedlings

(1) Fine boring machine. Choose the land with flat terrain, leeward sunlight, convenient water source, deep soil, loose fertility, convenient transportation, and easy operation and management as the sampan field. Prepare Sakata according to Sasaki and Honda from 1:80 to 100. Before sowing, turn (rotary) cultivating tillage field, leveling fine. Then it ditched the trampoline. The trampoline was 1.40 meters wide, the furrow width was 0.40 meters, and the furrow depth was 0.15 meters. The flat surface is required to thoroughly permeate the bottom water.

(2) Preparation of nutritious soil. Seedlings for the cultivation of the field need 750 kg of nutrient soil per hectare (for about 240 to 270 plates). Take fertile vegetable garden soil or loose paddy soil in advance to pour urine and manure, and add 2 kg of superphosphate stack in 100 kg, and then air dry and smash. The soil is mixed with Zanthoxylum sulphate before sowing, but the type and amount of Zhuang Zhe agent must be paid attention and must be tested first. Advocate the use of a strong agent that is suitable for the local soil properties instead of inorganic fertilizer. When bed soil is processed and sieved, mix 0.5-0.8 kg of drought-resistance strong agent per 100 kg of fine soil.

(3) Emissions from the tray. For floppy disk breeding, horizontal rows of two floppy disks, disk and disk flash overlap overlap, the bottom of the disk and the bed close to ensure that the disk is not deformed, no Alice angle.

(4) Spread the subsoil. Spread the subsoil on the sampan plate, with a thickness of 1.8 to 2.0 cm (approximately 2.5 kg of nutrient soil). After laying the screed, use a wooden screed to make the thickness uniform. After the soil is set, use a watering can to moisten the subsoil.

(5) Even sowing. The use of daily immersion night dew to make rice seeds to break the chest dew white. When sowing seeds, they should be sorted according to the seedlings, so that they can be sown uniformly and distributed in multiple times.

(6) Cover soil. It is better to cover the seeds with the nutrition soil that has been prepared without adding a strong antibacterial agent. There should be no mud on the border to prevent it from being crooked due to string rooting.

(7) Seedling management. The core of management within one week after sowing is the regulation of moisture, so as to keep the wet and dry conditions of the trampoline moderate. The mastery standard is: the top surface of the trampoline is not white and not watered. When watering, measures must be taken to make the water droplets atomized or refined. The large water droplets cannot be poured and poured; each watering can not form a product around the surface of the disk and the disk. Water, always keep the soil in the falling valley moist. It is emphasized that during this period, it is necessary not to allow the discs to dry and burst, nor to allow water to accumulate on the plate, so that the water and gas can be coordinated, and Li Zagan can be used to create strong and strong roots.

(8) Picking and transplanting. The floppy disk can be transplanted after transplanting. When transplanting, try to reduce the number of hoe block moving, so that it can be planted along with transportation, ensuring no deformation, no breakage, no injury to seedlings.
