What should be paid attention to before planting rice seedlings

Rice cultivation is very common in the south of our country. We all know that the staple food of southerners is rice. In fact, both southerners and northerners have a great demand for rice. Therefore, rice is the most common and largest planting area in the cultivation of agricultural products in our country.

What should be paid attention to before planting rice seedlings

Phosphate fertilizer and organic fertilizer were applied 10 days before transplanting of rice seedlings, 150 grams of superphosphate or calcium magnesium phosphate fertilizer were applied per square meter of seedling bed, 250 grams of mature peanut bran were retted and 300 grams were retted. The phosphate fertilizer and organic fertilizer were stirred and mixed evenly, then sprinkled evenly on the seedbed, and then sprinkled with a small amount of water, so that the fertilizer evenly fell into the soil of the root of rice seedlings and fully contacted with the soil. After transplanting, rice seedlings rooting early and quickly. There are many fibrous roots, developed roots, easy to turn green, strong seedlings, good tillers, disease resistance and insect resistance.

Matters needing attention in High yield harvesting of Rice

1. Drain the paddy fields as early as possible, and if necessary, dig trenches to drain the water from the lowlands as soon as possible.

2. More than 95% of the rice glumes are yellowed, the grains are hardened, and the rice grains are transparent, which can be harvested, and mechanical harvesting can be done a few days later.

3. If the weather is fine or the conditions permit, it is best to cut the sun manually, which can obviously increase the 1000-grain weight and increase the yield. At the same time, the commerciality of rice is good and the germination rate is high. If you use a harvester, it is best not to use a full-feed harvester (many branches, crushing the glume).

Benefits of raising seedlings in Rice greenhouse

The main results are as follows: 1. Raising rice seedlings in the greenhouse is beneficial to maintain the temperature in the greenhouse, the temperature difference between day and night in the greenhouse is small, and the anti-stress buffering ability is strong. Raising seedlings in greenhouse can be 5-7 days earlier than that in small greenhouse, making full use of the accumulated temperature in early spring and sufficient seedling development.

2. Improve the utilization rate of land and seedlings. Because of its large space, high all around, uniform growth of seedlings and no marginal waste seedlings, the seedling rate was significantly increased and the area of seedling field was reduced.

3. The greenhouse has large volume, large lighting area, good heat preservation performance and balanced temperature in the greenhouse, which improves the utilization rate of light energy and facilitates ventilation, which is helpful to seedling refining.

4. The quality of seedlings in greenhouse is generally better than that in greenhouse. Due to the appropriate temperature difference between day and night in the greenhouse, it is conducive to seedling growth and dry matter accumulation, and improve the quality of seedlings.

5. The cost of raising seedlings is low. Raising seedlings in greenhouse saves labor and species and is beneficial to the management of seedbed. Therefore, seedling raising and management can all be carried out in the shed, which is not limited by the day period, and the labor intensity is reduced.

Shallow Wet and thin Sun Irrigation technique for Rice

1. Rejuvenation period. The mastery of the shallow water layer during the return to green period should be determined according to the specific situation. For the seedlings with longer age, the water layer can be deeper, otherwise it can be slightly shallower.

2. Late tillering stage. In this stage, the time and degree of drying the field must be strictly controlled in order to give full play to the role of drying the field, neither too early nor too late will affect the tillering, too late will affect the differentiation of young ears. The time of drying the field should be from late tillering to young panicle differentiation, and the degree of drying depends on the field, seedlings and weather. At the same time, according to the conditions of the water source and the channel of the irrigation area, the field should be dried in pieces to avoid drought caused by untimely irrigation and affect the growth of crops.

3. Heading and flowering stage. The yield of rice at heading and flowering stage will be reduced due to high temperature. When the summer temperature reaches 35 ℃, it will affect the pollination and fertilization of rice flowers, and reduce the seed setting rate and 1000-grain weight. In order to prevent the damage of high temperature in summer, the irrigation water layer should be deepened appropriately.

4. Yellow mature stage. At this time, we can not dehydrate prematurely, dehydration prematurely will make the soil dry, force to mature, affect the fullness of grains and reduce the yield of rice. At the same time, do not make too much water, otherwise it will delay ripening, increase the number of green grains, and at the same time is not conducive to harvest. It is usually necessary to dry the fields, which is good for the harvest.

Rice cultivation is very common in our country. Before planting rice, growers should know more about the planting methods and techniques of rice, and with the continuous development of society and the continuous progress of technology, the techniques and methods of planting rice are becoming more and more advanced.
