Planting method and time of red bean

Red bean is one of the whole grains. After its nutritional value and efficacy have been vigorously publicized, people's love for red bean has reached an unprecedented height. We often use red beans in our daily life, and we often use foods made with red bean-flavored raw materials, so for the new generation of young people, we really don't know when red beans were sown or how red beans should be planted. Here's a pro-farm network to tell you the answer, and hope to help farmers who grow red beans.

Planting time

Red beans in different regions have different termination time, growth cycle and so on. Red beans can be planted for two seasons in some areas, while sowing can only be carried out in one season in many areas. Let's take the planting time in most areas as an example, which is usually the best during the period from the end of May to the beginning of June, when the temperature is basically stable at 20 to 28 degrees, and there is plenty of water during this period, which is very suitable for the germination of red bean seeds. Of course, you can plant it a little later, but there will be a drop in yield.

Planting method

1. Rational selection of species

At present, there are many kinds of red bean seeds in the market, including big red bean and small red bean, in which big red bean and small red bean are divided into many kinds, so the first thing we should consider in seed selection is the yield of red bean, the second is whether the germination rate of seeds is high, and the last is the various resistance of seeds. We will select red bean varieties suitable for local cultivation according to the soil of different regions as well as climate, temperature, Rain Water and other factors. At the same time, no matter whether the variety is good or not, we can not buy old species, the survival rate is too low, the loss is too great.

2. Scientific land preparation

Because the red bean itself is more adaptable to the environment than other crops, we can choose to ignore the choice of planting land, but one thing that must be considered is that the moisture in the planting land should not be too much, that is, the soil moisture should not be too high, which can not easily affect the yield. In the process of soil preparation, we need to clean up all the debris in the field, turn the soil deeply, then sprinkle a layer of lime to eliminate bacteria, and sprinkle a layer of livestock manure or plant ash in the sun for about ten days. Then make ridges and ditches and wait for sowing.

3. Sowing method

The skins of red beans are relatively hard, and if they are sown directly, the germination rate of the seeds is particularly slow, and the germination rate is not very high, so before sowing, we need to soak the red bean seeds in clean water for about 20 minutes, place them for about 20 minutes, rinse them with clean water, and then sprout them in an environment with a temperature of 25 degrees. After about five days, we can sow the seeds. There are two ways of sowing: one is to dig a small hole in the soil at an interval of 30 centimeters, sow three seeds in each hole, and then cover the seeds with the soil. The other is to first cultivate the seeds on the seedling bed and wait until the seedlings grow out of about ten centimeters before transplanting according to a certain density.

4. Fertilization technology

The fertilization of red beans needs to have technical content, and should not be fertilized at random. Fertilization should not be too much, which will lead to the growth of seedlings without pods, too little fertilization, pods not full, poor quality, and incorrect types of fertilization. can lead to plant necrosis or disease. During the whole growing period, fertilizer needs to be applied twice, the first time is to raise seedling fertilizer, that is, about a week after planting, an average of 100 jin of urea, 50 jin of phosphate fertilizer and 30 jin of compound fertilizer should be applied per mu. The second fertilization is to wait until the red bean seedlings enter the flowering stage to produce pods, which is the period when red beans need the most nutrients, and it is also a critical period to determine the yield. We evenly spread 300 jin of farm manure, 100 jin of potash fertilizer and 50 jin of boron fertilizer per mu.

5. Disease prevention

Red beans are highly resistant to diseases, so there are few diseases and insect pests in general, but there are occasional rust, aphids and leaf rollers. The most effective control method is to spray 5% triadimefon wettable powder 1000-1500 times, or 40% Fuxing EC 8000 times, or

50% verapamil EC 800 times, or 50% sulfur suspensions 200 times, sprayed once every six or seven days, two or three times. For aphids and leaf rollers, trichlorfon solution or dimethoate emulsion is mainly used for spraying.
