What should I do if the wheat seedlings are not coming out together?
At the initial stage of sowing and emergence, if the wheat field with uneven emergence of seedlings resulting in insufficient basic seedlings is found, the emergence of seedlings can be distinguished and the following measures should be taken to prevent and control.
First, timely replanting in order to ensure the whole seedling, check the seedlings in time after the emergence of wheat seedlings, for the wheat fields with uneven emergence, resulting in serious lack of nests and broken strips, it is necessary to replant with seeds of the same variety at the initial stage of seedling emergence.
Second, transplanting and thinning in the wheat three-leaf stage is better for the emergence of seedlings in the whole field, and only a few wheat fields with lack of nests and few seedlings can be transplanted in Honda with sparse soil and fixed root water after transplanting. When transplanting, the heart should not be exposed under pressure, water should be watered after burying the soil, and fertilizers should be properly applied to slow down the seedlings.
Third, for those who lack seedlings due to drought, timely watering should be done once a day for 3-5 days, so as to promote the normal growth of wheat seedlings and more strong tillers. For those who hurt the seedlings due to improper application, they should be watered for 2-3 times and then loosen the soil after watering.
Fourth, topdressing to promote strong seedling emergence is relatively uniform for each litter, but the wheat field with insufficient basic seedlings can be dominated by quick-acting nitrogen fertilizer from emergence to three leaves, and suitable seedling fertilizer can be applied early. It can promote early tillering, strengthen tillers, optimize individuals, achieve strong winter and early onset, and win high yield.
5. If the lack of seedlings is caused by sowing too deep, part of the covered soil can be removed, combined with irrigation and ploughing to improve soil ventilation and promote the development of lateral roots.
6. the diseases and insect pests that often occur in wheat before winter are mainly root diseases and underground pests. Timely control measures should be taken to eliminate diseases and insect pests so that the thin wheat seedlings can be turned into strong seedlings as soon as possible.
Seventh, to prevent salt damage caused by salt damage caused by lack of seedlings in wheat fields, should be timely ploughing and loosening soil, reduce ground evaporation and prevent salt return. The salt content of soil was reduced by irrigation and washing salt or opening trench to discharge salt.

California brome
California brome is a perennial, tufted forage with wide and long gray-green leaves and high leaf / stem ratio. The biggest morphological difference between California brome and awnless brome is that it has no underground rhizome. The soil requirement of California brome is similar to that of awnless brome, and its cold resistance is slightly worse than that of awnless brome, but its heat resistance is significantly shorter than that of awnless brome, and most varieties can be used for 6-8 years. California brome has a high leaf / stem ratio, its feeding quality is better than that of awnless brome, and its yield is similar to that of awnless brome. California brome is suitable for the east of China.
