Quick frozen sweet corn kernel raw material sweet corn kernel weight is one of the three elements of yield. Increasing grain weight is an important problem in High-yield Cultivation of sweet corn. In order to improve grain weight, we should first understand the increasing law of grain weight and the period determining grain weight. The grain weight depends on the size of "grain storage capacity", the speed of grain filling and the length of grain filling time (different according to different types).

After fertilization, the volume of sweet corn increased rapidly. Generally, from pollination to about half a month after pollination, it is not only the key period to determine the grain size, but also the key period to promote the grain to become larger.

The process of transporting photosynthetic products from leaves and nutrients stored in stems and sheaths and absorbed by roots to grains is called grain filling. According to the research on sweet corn, the first few days after pollination is the initial stage of grain organ composition, and the filling speed is slow; About one week after pollination, the grain filling speed increased rapidly, and the grain entered the rapid grain filling stage. More than half a month after pollination, it reached the peak stage of grain filling, and then fell slowly. Therefore, this stage is the key period for determining grain weight and improving grain weight in consumption.

The length of grouting time depends on species characteristics, soil and climatic conditions after pollination. The filling period of late maturing species is long; The early maturing species have short filling period. After pollination, if the soil moisture and nutrition are lack or the temperature is high, the filling period becomes shorter; If the soil moisture is suitable, the nutrition is sufficient and the temperature is low, the filling period is long and the seeds are plump. Pay attention to watering after pollination, which can prolong the grouting period and improve the grain weight.

The above is the details of the key period of determining the weight of quick-frozen sweet corn kernels. Welcome to consult our company!
