The latest sugar beet low yield reasons

Sugarbeet is another source of sugar besides sugarcane, which has high economic value, but the yield of sugarbeet can not go up because of the lack of cultivation techniques. Now the cultivation problem has become the main factor restricting the development of sugarbeet. So what is the reason for the low yield of sugar beets? How to solve the problem? Let's get to know it.

1. Continuous cropping and continuous cropping

Sugar beet generally has the problem of short years, and many farmers often adopt the method of continuous cropping, which will lead to continuous consumption of soil nutrients and moisture, resulting in soil hardening, resulting in poor growth of sugar beet, generally after continuous cropping for 2-3 years. Sugar beet will reduce its yield by about 20% and 35%.

Solution: for this situation, it is necessary to change crop rotation reasonably, to carry out rotation for more than 6-7 years, and to put an end to continuous crop rotation, and at the same time, sugar beet is more sensitive to herbicides, which will also lead to accidents of reducing its yield. therefore, try not to use high residue when using herbicides.

2. Insufficient fertilization

Sugarbeet needs crops with large amount of fertilizer, and high yield can be obtained by scientific and reasonable fertilization when planting. Due to the lack of planting knowledge, many farmers mostly use a small amount of farm fertilizer, no chemical fertilizer or less. So the sugar beet does not have sufficient nutrients to grow, resulting in low yield.

Solution: for this situation, we should broaden the source of fertilizer and apply more organic fertilizer, which can not only promote the root expansion of sugar beet, but also alleviate drug damage and increase production and income. In the sugar beet growth period, ah, scientific and rational application of chemical fertilizer, mainly phosphate fertilizer, supplemented by when, generally in the growing period to topdressing 2-3 times, each time 10-15 kg per mu, 20-30 kg of diammonium phosphate, 8-10 kg of potassium sulfate.

3. Planting is too sparse

The unit area treatment of sugarbeet is composed of root weight per plant and effective plants per unit area. If the weight per plant is high, but the number of populations is small, its yield is also relatively low. Farmers in many areas have the habit of sparse planting, generally controlling the row spacing at 30 × 70 cm or 40 × 70 cm, which leads to low sugar beet yield.

Solution: for this case to appropriate close planting, reduce the plant spacing, increase the total tree, the general plant spacing is controlled between 20 × 60 cm or 30 × 65 cm.

4. Diseases and insect pests

In recent years, sugar beet diseases and insect pests become more and more serious, some farmers do not pay attention to sugar beet diseases and insect pests or do not know what to do, do not control the disease in time, resulting in more and more serious diseases and insect pests, some sugar beets are almost eaten up by pests, resulting in a substantial decline in yield. According to the survey, after sugarbeet is infected with brown spot and root rot, the general yield will decrease by about 20%.

Solution: we should pay attention to the prevention and control of sugar beet diseases and insect pests, focusing on the prevention and control of night bandit, root rot and brown spot. Phoxim is also used to control the disease. Methyl topiramate can be used to control the brown spot disease. Carbendazim or chlorothalonil can be used to control root rot.
