Three details to pay attention to in the cultivation of rice
With the improvement of production technology, farmers use many advanced planting techniques in the process of planting rice, but some details are often overlooked in the production process, affecting the yield of rice and reducing the benefits. Now we will discuss some points for farmers. reference.
(A) Autumn breeding bed
Whether it is the springtime breeding bed or the autumn breeding bed, the labor is the same. It is only the first year of autumn that the bed has more advantages than the second year of the spring.
1) The degree of soil maturation in high autumn bed, the soil can turn 20 to 25 cm deep, conditional rotary tilling is better, after a fall and winter ripening, the second year of the spring continues to mature, obviously longer than the spring soil bed aging, so that Increased humus content, and appropriate sowing of farmyard fertilizers, created favorable conditions for the development of spring broth.
2) Kill the eggs in the autumn to make a breeding bed. Turn the eggs that have infiltrated into the soil on the ground surface. When the winter comes, it will be frozen or eaten by birds to prevent rice seedlings from being harmed by pests and diseases.
3) Increase the bulkiness of the soil After the autumn ploughing, with a certain amount of moisture freezing, the expansion of the soil is implicated, until the spring of next year, the volume shrinks slightly, forming the automatic collection of the soil, this rise occurs, Not only increased the bulkiness of the soil, but also caused the eggs to be crushed to death. The germinated grass seeds were frozen to death.
(II) Paddy rice lodging and binding
In the late stage of rice growth, it was prone to lodging because of many reasons. When farmers friends saw it, they would throw a handful of them. In fact, this practice is harmful.
In general, 3 to 5 days after lodging, the plant leaves and cobs will self-pick up, especially in fields where the lodging is less severe, and the plants will automatically adjust, but the natural sequence of the panicle, panicle, and leaf will be destroyed after lodging. The increase in mechanical damage will result in a greater reduction in production losses. This should be done after lodging the rice.
1) Timely ditching drainage can reduce the spread of sheath blight, prolong the functional period of the leaves, ensure that the grain can continue to grout, and have a positive effect on the reduction of neck rot.
2) Rice with early spraying of fertilizing medicine should be mixed with fertilizer and medicine. It can use 150g of potassium dihydrogen phosphate per acre, add 5% of high-performance cypermethrin 50ml, or use Green Wind 95 to prevent disease nutrition regulators. 100 ml plus 10% of a net of 20 grams, or use 100 grams of multi-effect vitality, plus 12.5% ​​of Brin 10 grams for spray remediation, in the application of the above fertilizers are required to add water 50 to 75 kg, formulated The thin liquid spray, such as the mixture of 15% of Su Bin 45 grams, you can also rule rice false smut, sheath blight.
(III) Herbicides after Harvesting Paddy rice is a post-harvest part of rice harvest. Many farmers do not consider the problem of herbicide after harvesting. However, it is not true. In particular, weeding is performed immediately after harvest, which is more effective and will be planted in the coming year. Rice is beneficial. Here are some methods for harvesting grass after harvest:
1) Induced sprouting of rice seedlings After harvesting, the rice immediately fell to the ground, followed by a slight high temperature in autumn and autumn. It was sufficient to meet the bud germination temperature, and applied lime nitrogen or other available nitrogen fertilizer to the field in order to induce The germination of the ground grass seed (if not enough to turn over, turn it into the second year of the spring, but also in the paddy field to apply lime nitrogen, induce grass seed to shoot quickly), just when the cotyledons, winter is freezing dead Even if there is no recurrence in the next spring, prevent grassland from harming rice.
2) After the rice is harvested and harvested, the rice is transported back to the courtyard. We can deliberately incinerate the rice husks. In order to make the effect more significant, some flammable hay can be scattered in the rice fields in the past to facilitate the burning and to make the seeds lose. The ability to live, to kill the purpose of weeds.
