Wheat, rapeseed, green manure "spring equinox" seedlings

First, the characteristics of climate and seedlings.
After the "stunning" solar terms, the overall temperature rises faster, but the sunshine is insufficient and the rain is more, which is quite unfavorable for the long spring of wheat, oil and green fertilizer.
The overall characteristics of this issue are:
1. The second wheat enters the jointing and booting stage, and the birth process is postponed.
The average total number of wheat and barley seedlings was 477,000 and 495,000 respectively, an increase of 73,000 and 64,000 respectively over the previous year; the seedling height was 33.6 cm and 35.1 m, which was 5.5 cm and 5.4 cm lower than last year; the leaf age was 8.1 and 8.5. It was reduced by 0.5 sheets and 0.5 sheets respectively compared with last year; 4.2 sheets and 4.4 sheets of green leaves were reduced by 0.3 sheets and 0.3 sheets respectively compared with last year. From the perspective of the birth process, the two wheats entered the jointing and booting stage, the total number of seedlings was in the stage of seedling reduction, and the growth period was postponed for about 3 days.
2. The growth of rapeseed is close to the normal level, and the fertility process is slightly delayed.
The average leaf age of rapeseed was 24.3, 14.1 green leaves, 4.1 new leaves, 1626.2 square centimetres of leaf area, 1.51 cm thick root neck, 1.11 cm thick moss, 12.2 cm high moss and 1.8 branches. Compared with the same period of last year, the leaf age decreased by 0.5, the number of green leaves decreased by 0.5, the new leaves decreased by 0.4, the leaf area decreased by 130.2 square centimeters, the root neck decreased by 0.11 cm, the moss thickness decreased by 0.51 cm, and the moss height decreased by 31.1 cm. Branches are reduced by 3.5.
3. The growth of green-fermented broad beans began to turn better, but it was still worse than last year.
The average plant height of broad beans is 22.11 cm, 10.32 green leaves and 3.98 branches. Compared with the same period of last year, the plant height decreased by 1.71 centimeters, the branches decreased by 0.87, and the green leaves decreased by 0.44.
Second, the next stage management opinions.
At present, wheat, oil and green manure have entered the spring stage, and the second wheat is in the stage of jointing and booting. The rapeseed is about to enter the initial stage of flowering. The growth center begins to transfer from vegetative growth to vegetative growth and reproductive growth, which determines the yield. Critical period. In view of the characteristics of individual growth in winter this year, in field management, we must emphasize the promotion of weak control, promote balanced growth, strive for effective tillering and effective branching, focus on building production shelves, and do a good job in clearing ditch and disease prevention. Weeding work creates a more suitable field environment for winter growing.
1. Look at the seedlings and apply the ear fertilizer and the Linhua fertilizer.
Ermai: For the fields that have not been applied to the jointing fertilizer, the panicle fertilizer should be applied. Spike fertilizer applies 5 to 7.5 kg of urea per mu. Farmers with conditions can increase the application of compound fertilizer or BB fertilizer in an appropriate amount of 10 to 15 kg per mu. For the field where fertilization is more in the early stage and the growth is strong, the fertilization time should be postponed appropriately. After the leaves are faded and yellowed, apply the panicle fertilizer.
Rapeseed: Fields that have not applied spring moss fertilizer and fields that have premature senescence should be applied to the application of Linhuafei, especially the live rapeseed with poor growth. It should pay more attention to the application of Linhua fertilizer and increase the number of corn kernels in rapeseed. Generally, 5 to 10 kg of urea is applied per mu in the initial flowering period.
2. Clear the ditch in time.
In spring, there is a lot of rain. It is necessary to do a good job of cleaning the ditch system, improve the quality of the ditch system, make the ditch and ditch communicate, unimpeded and unimpeded, reduce the damage of spring rain and waterlogging, promote roots and roots, and improve the ability of crops to resist disasters and avoid disasters.
3, pay attention to the disease dynamics, do a good job of spring.
In the middle and late period, it is a key period for the control of two wheat and rapeseed diseases. According to the opinions of the plant protection department, we should do a good job in the control of aphids, wheat powdery mildew, scab, rapeseed sclerotinia and other diseases and weeding in the field.
