Previously, people in the countryside, in addition to breeding a variety of poultry, livestock, can support the family's planting industry can not be less; like the ground can be planted in a variety of crops are also quite a lot, and as the world's three major potato crops, one of the cassava, especially good seed, adaptable, drought-resistant, barren, as we all know, in the past in the rural areas of our family planted cassava, as long as there is a little bit of space on the side of the mountain at home, to plant a few root and root cassava are not a waste of ground, are put to plant. Planting a few root and stem cassava are not a waste of land, are put to plant. Mainly for several reasons: First, the development and utilization of the way less, in addition to the production of starch and as raw material for ethanol no more high-value use; Second, the production of low efficiency, large inputs and outputs of small; Third, the local have more high economic value of the crop in the development of the direction of the change in the use of land.

What caused this? Cassava planted for a long time will be relatively speaking less, in addition to large-scale engaged in planting and in mass production of other growers are relatively few, the main reason I think it is still aging, a small number of farmers planted relatively to them to bring the value of the experience is not very high a toxicity, many of the younger generation of people do not know enough about it, in the edible can not be done like the older generation so much attention, coupled with the fact that now the life of rural areas Diversified, there are many other options.

With the improvement of people's living standards, the demand for cassava's weekday life is not too great, resulting in a very small space for price enhancement, the grower's earnings are not high, so gradually on the grower is less and less. Cassava is rich in starch, its content is between 25 a 32%. And contains protein, fat, vitamin A, B and other nutrients. Cassava by washing and soaking treatment heat processing is generally edible, however, lignified, moldy cassava is toxic, pay particular attention to not eat raw.

Since it is one of the three major potatoes, cassava and potatoes, sweet potatoes, is edible, and cassava is not only people can eat to fill their stomachs, such as chickens, ducks, pigs and other livestock can be crushed cassava flour mixed to feed, cassava leaves to feed the fish. Tapioca leaves are used by farmers to feed poultry and livestock in the past, and are easy and quick to collect. The fresh leaves can be fed to rabbits, and those that are not eaten can be dried as an addition to pig food.
