The main points of the latest course of Rice Seedling raising techniques and methods

Rice is one of the main food crops in China, especially in the south of China. Generally speaking, after the Beginning of Spring, most areas began to prepare for rice seedlings, so how can we make the seedling rate higher when raising rice seedlings? Grow better? Is it more resistant? Here are a few key points of rice seedling raising technology, which we must master when raising seedlings. Let's take a look.

1. Seed treatment

Rice needs to be treated with seeds before raising seedlings, which can improve the germination rate of seeds and thus the emergence rate of rice seeds. First of all, it is necessary to sun up the seeds; then soak the seeds with Baike or Prochloraz and water for five or six minutes; then soak them with imidacloprid wettable powder for two days; finally, accelerate germination and wait for about 80% of the rice seeds to sprout white, then you can sow the seeds. This can not only improve the emergence rate of rice, but also improve the disease and insect resistance of rice.

2. Water management

Water management during rice seedling raising is also very important. In general, the moisture of the seedling land does not need too much, it is generally able to soak the border surface, and the second is that when the moisture in the field is reduced, it should be watered properly and the humidity can be kept in the original position. The moisture in the rice seedling field should not be too much, otherwise it will affect the emergence of rice seedlings, but also cause diseases and insect pests, resulting in seedling death. If it is to raise seedlings in dry land, we should timely water the film, water the soil thoroughly, prevent the death of seedlings, and maintain a reasonable humidity in the seedling field during the period of emergence.

3. Fattening management

The fertilization management of rice seedlings can also be divided into two ways: dry field and paddy field. Generally speaking, when raising seedlings in dry land, the nutrients required are not very large. Generally speaking, under the condition of sufficient base fertilizer, there is no need to fertilize them in the later stage, so as to avoid burning seedlings due to excessive fertility, but if the bottom fertilizer is not properly treated, the leaves of the seedlings are yellowing, so timely fertilization is needed. When raising seedlings in paddy fields, the amount of fertilizer required is relatively large. When fertilizing, we usually apply fertilizer on the principle of frequently applying thin fertilizer to prevent the occurrence of burning seedlings and promote the growth of seedlings.

4. Pest control

In order to avoid the impact of diseases and insect pests on the growth of rice seedlings, it is generally best to apply 48% chlorpyrifos EC and 35% phoxim microencapsulated granules before sowing, with a dosage of 150 ml and 1 kg per mu respectively. After sowing, in order to prevent the harm of underground pests to rice seeds, we also need to sprinkle an appropriate amount of 40% phoxim EC around the seedling field. After the emergence of rice seedlings, we mainly want to avoid the harm of Rhizoctonia solanacearum, bacterial wilt and leaf-eating pests to the seedlings. We can use benzyl dichloride, bensulfuron-methyl dichloroquinolinic acid and imidacloprid wettable powder plus Shikeduke respectively.

These are the four key points when everyone is sowing and raising seedlings of rice, and they are also the key to raising seedlings of rice. Generally speaking, as long as we have a good grasp of these points, the cultivated rice seedlings are excellent, and they are also of great benefit to the later field operation.
