Nanjing Jiangning friends warm home like March 11 WeChat: What is this rapeseed? This is the case with the cracking of the rapeseed of the rape, which is almost full of fields.
User Yuelu Shanren: It should be the temperature in the early period is relatively low, caused by the recent temperature rise. Rape is more sensitive to boron, boron deficiency may also occur in this situation, appropriate application of boron fertilizer.
Water clear: The direct cause of cracking of rapeseed stems is frost damage, occurring shortly after the sudden frost weather. During the period of bolting and flowering, rapeseed stems were frozen and their growth was stopped or slowed down. The temperature rose after the low temperature, and the stems continued to grow rapidly. The stem cell proliferation caused turgor pressure, which caused the cracking of the epidermis. Therefore, cracking of stolons occurs only a few days after sudden frost, unlike the young leaves of wheat seedlings, which can show symptoms such as withered spots on the day after frost.
Different rape varieties have different degrees of springness, and there are differences in cold resistance and frost resistance. The same variety, different planting dates, different fertility processes, and frost resistance and the degree of cracking of stolons will not be the same. In the same variety and under the same planting conditions, because different plots or different plots in the same field have different fertilizer and water conditions, their growth potentials are different. Fast growing stolons are more tender and vulnerable to frost, and because of their strong growth potential, they are frozen. After the temperature rises quickly, the stolons are more likely to crack.
Jun warm like home: The adjacent field rapeseed varieties are different, there is no such situation. In the afternoon, I went to other towns and towns to look at it. Other varieties were all good. Farmers reflected this kind of situation.
Clear water: Look at the difference in the fertility of other rapeseed varieties.
Netizen professional farmers: I think Shuiqing analysis makes sense. There are no other diseases or phytotoxicity symptoms on the affected rape plants. Only one species in the local area has this kind of situation. It may be that the frost resistance of this species is not very good. The lack of boron in rapeseed generally does not cause cracking of stolons. Its main features are that the leaves become smaller, thicker, brittle and harder, and the color is deeper, “flowers are not realâ€.
