Up to the winter potato season, many farmers were confronted with the same problems: the same plots, the same varieties of potatoes, the high proportion of potatoes used to produce them, the low value of their own small potatoes, the low value of their acreage。
There are three main reasons for this reduction: the incorrect application of fertiliser nodes, the imbalance in fertilizer ratio and the lack of trace elements such as potassium zinc. Many farmers apply bottom fertilizer only once, do not catch up later and do not have sufficient nutrient supplies. A four-stage fertilisation process would lead to a steady high yield。
First, to apply bottom fat and to build high bottoms。
Organic and bacterial fertilizers are all used as a single application. Per acre, common well-established areas are used for compound fertilizer of 40-45kg, potassium sulphate of 10-15kg, which is used for consumable farm fertilizer, plus zinc weight of 1 kg. Red zone, sandy, poor diet, with options of 45-50 kg for the exclusive decomposition, 10% decomposition, 200 kg organic or 40 kg microbiological. Be careful to separate the fertilizer from the potatoes and prevent the burning。
Potato sowing
Ii. The fertilization of the seedling season will encourage it to grow。
The seedlings grow from 4 to 6 real leaves (25-35 days after seeding), are weak and underweight, with 6 to 8 kilograms of urea per acre, and contribute to the growth of the roots and growth of the seedlings. Fat and early, avoid burning roots. In winter, low-temperature seedlings are a high-yielding base
Potato seed
Iii. Re-enactment of the tubers to increase fattening and to widen the production gap。
The planting of 50 to 70 days into the current expansion period is the highest demand. The timely removal of buds reduces nutrient consumption, and planters can be controlled with fentanyl. I don't care if i go after urea alone. Potassium sulphate, 8-12 kg per acre, accompanied by a small amount of urea, is sprayed with zinc fertilizer on the frontal lobe. At the same time, 10 centimetres of soil are cultivated in order to avoid the lighting of chips into green potatoes。
The potato boom
Iv. Replenishment of yams to prevent early decay and increase weight。
During the 20-30 days before the harvest, the root system lost its ability to absorb fat, and urea was prohibited to avoid the browsing. Potassium dihydrophosphate sprayed on the side of the leaf with bovine oscillation on the side, which is applied once in 7-10 days and twice in a row, slows the aging of the leaves, increases the proportion of the large potatoes and reduces hollow malformations. In the winter and spring, it's very wet。
Avoiding the application of four faults: nitrogen-heavy potassium; no rapid urea application during the swelling period; no bottom application without pursuit; and no neglect of trace elements such as zinc。
Potato harvest
The high production of winter potatoes does not depend on the blind use of more fertilizer, the control of four fertilizing stages, and the integration of organic fertilizers into the red border, taking care of the fields, control and prevention of diseases, will enable the production of small and deformed potatoes to be avoided and the production of good products to be stabilized. Have you ever had any problems with empty potatoes? An exchange of comments is welcome. The next issue, on wheat fertilisation, would welcome attention。
