A, sowing time

Winter and spring type Sherry red general late September sowing, autumn Sherry red late July sowing. Specifically according to the characteristics of varieties, edible requirements and stubble arrangements and other conditions.

Two, planting method

1, seedling: seedling is an important step in the planting of red snow, seedling soil to be very fertile, preferably one month before the seedling can be composted with farmyard manure and then seedling. Seedlings before tilling good, the use of sunlight to achieve a certain effect of sterilization. Selection of soil to choose a relatively fine place, the seeds do not have to be buried very deep, 2-3 centimeters is good, so that the seeds can be well absorbed by the land nutrients and breathing air, which will help faster seedling success.

2, land preparation: the soil after plant removal is not demanding, a little fertile is good, the land or compost, and the amount of base to be a little larger. Secondly, the land will be leveled into a strip, drainage should be good, each control in 1.5 meters wide, the middle of the drainage ditch control a foot wide more than their own, to ensure that the daily management of the convenience of walking on the good. Clean out the weeds and so on to take away, can not be composted, or easy to produce pathogens.

3, planting: planting time to be a little early, this time the best vitality of the red snow, high survival rate, time control in the 8-10 o'clock or so. Fixed value of the seedlings above the best to have a certain amount of soil, so that the seedlings can form an effective protection. It is recommended to transplant at about 12-15 cm, when the seedlings are just about to enter the growth period, too dense not in favor of growth. Transplantation of seedlings control in 20-30 cm spacing, transplantation must be watered after a certain amount of water.

4, fertilizer: fertilizer is the determining factor in the late growth of the red snow, so the fertilizer must be sufficient. Fertilizer is generally mixed with nitrogen fertilizer phosphate and potash fertilizer together with the majority of nitrogen fertilizer station. In order to ensure the growth of seedlings in the early stage can also be applied to a certain amount of urea, a week after planting needs to be timely fertilization, a small amount. The middle period is the most diligent time to fertilize, usually need to apply 2-3 times. Half a month before picking there is no need to fertilize. After each application of fertilizer according to the soil dryness and humidity of the appropriate amount of spray water.

5, pest prevention: this is the snow red need to pay attention to the place, it is easy to cause a reduction in production. The main damage to the red snow is focused on insect pests, like aphids and other occurrences are particularly frequent, and not easy to find. Generally found that the leaves of the snow red vegetables have a tendency to discoloration, we should promptly go to check the plant. For insect pests to find the type of timely use of chemicals to remove, because artificial is very difficult to find. Other diseases occur less, as long as the humidity is controlled and the water is not too high.

Means of controlling diseases and pests of the snowy red

Mainly pests and diseases are virus diseases and aphids.

1, the principle of prevention and control of the implementation of "prevention-oriented, integrated control" of the plant protection policy, to promote "agricultural control and biological control, reduce chemical control, promote physical and biological control" of the principle of pollution-free management. Aphids, virus diseases as the focus of control.

2, pesticide prevention and control of viral diseases in the early stages of the onset of the selection of 20% virus A wettable powder 500 times liquid or 2% of the bacterial grams poisonous grams of 250 times liquid and other viral inhibitors and growth promoters used in conjunction. Aphids selection of 10% once again net wettable powder 1500 times liquid or 0.36% of the bittersweet alkaline water 1000 times liquid and other pesticide control. Alternate medication, the use of high toxicity and high residue pesticides is strictly prohibited.
