Several Advanced Methods of Rice Seedling Planting

The main results are as follows: 1. In the improved intensive cultivation, the tender seedlings with 3 leaves to 4 leaves should be planted early, the fields with good water sources should be planted early, and the fields with poor water sources can be a little later, and both dry seedlings and water seedlings should be applied, but they should be fully fertilized, deeply ploughed and raked flat, strong seedlings should be selected as far as possible, and seedlings should be planted in shallow water; the spacing between rows and nests is 1 foot 3 inches, and the spacing of 3 individual plants in each litter is triangular. This planting method is sparse in density and dense in sparse, which reduces the competition between nutrients and sunlight to the greatest extent, and is beneficial to the individual development of plants, so it can greatly increase production, so it is the most advocated way of planting seedlings.

2. Generally, the seedling age of wide and narrow row cultivation is 4 to 6 leaves, wide row is 1 foot 2 inch, narrow row is 6 inch, the distance between nests is 6 inches, about 10,000 nests are planted per mu, a single plant is planted in each litter, and two plants are planted in weak seedlings. To achieve east-west direction, rope planting straight, conducive to ventilation and bright line, reduce the harm of diseases and insect pests, enhance the photosynthesis of the middle and upper leaves in the middle and later stage, increase grain and weight, so as to increase yield.

3. Wide and narrow rows of mixed glutinous rice are planted on the basis of general wide and narrow rows, one row of glutinous rice (commonly known as wine millet) is planted every two wide rows, with 3 to 5 plants per litter, ranging from 1 foot 2 inch to 1 foot 5 inch. Pay attention to seed soaking and disinfection to prevent rice blast. Hybrid rice and glutinous rice are sown and planted at the same time. Due to the rational use of space to increase glutinous rice, coordinated growth with hybrid rice, and effective control of rice blast, it can increase yield.

4. Wine and millet seedlings are planted in a row of hybrid glutinous rice seedlings every 5 feet 5 inches, that is, five rows of hybrid rice are planted in the box, with 6 inches apart, 3 to 5 seedlings per litter, and single plant per litter of hybrid rice. This kind of planting method saves labor and time, reduces diseases, gets all kinds of glutinous rice, and is more popular.

5. Wide and narrow plants are planted in east-west direction, rope transplanting seedlings, 6 inches between nests, 9 inches between rows, 11000 nests per mu, single strong seedlings per litter, suitable early planting and shallow planting, which is beneficial to early growth and rapid development and increase effective panicles. The advantages of this planting method are convenient, ventilated and transparent, reduce diseases, promote individual development, form reasonable groups, and help to increase production and income.

6. the planting frame for planting seedlings is 6 × 10 inch, one plant is planted at each intersection, 10,000 nests per mu, a single strong seedling is planted in each nest, the east-west direction is required, the drawing is straight and even, the field is flat and thin water, it is convenient to plant as long as you can see the printing, and the root is stable and rehydrated after planting. One or more people can operate, which is relatively standardized, and combines the advantages of various planting methods, which not only saves labor but also increases production.

7. In the east-west direction of semi-arid planting, the rope is trenched and ridged every 1 foot 8 inches, the ridge tile is back-shaped, water is stored in the ditch, the ridge surface is moist, two rows are planted in each ridge, the row spacing is 5 to 6 inches, the nest spacing is 6 inches, each litter is about 10,000 plants per mu; generally, the planting point is basically the same as the water level, and the seedlings are planted in the middle. This planting method is not only beneficial to root growth and individual development, but also ventilated and transparent to reduce the harm of diseases and insect pests, and can also be used in paddy fields to promote a good harvest of both rice and fish.

8. Throwing seedlings is suitable for dry cultivation of plastic film seedlings on the seedling plate, and the seedlings are planted at about three leaves. The field should be flat, the water should be shallow, and the good dosage should be calculated. Generally, about 18 trees per square meter, that is, planting 12000 nests per mu, people stand on the ridge of the field, throwing them high, far and evenly with skillful force, scattered, showing a parabola. The standard planting method of pulling rope can also be adopted without throwing, which can also achieve the effect of increasing production and income.

It is worth noting that no matter which method of planting seedlings, there are seven common points: first, shallow, uniform, stable, and straight; second, seed coating or seed soaking to disinfect and cultivate strong seedlings; third, re-application of field bottom fertilizer to promote early growth and rapid development; fourth, to remove inferior diseased seedlings to plant large and strong seedlings; fifth, to avoid high temperature time to plant seedlings; sixth, Tianping thin water seedlings; seventh, whether to plant "Shuntianwan" in the east-west direction.
