Where is yellow cauliflower suitable for growing? How to manage in planting?

Yellow cauliflower is a perennial herb belonging to the genus daylily in the family of lily, mainly with flower buds as the product, and its aliases are called daylily, golden needles, yellow flowers, Chuanchuan grass, anserine, and yellow flower seedling and so on. Yellow flowers can be dried by dehydrating them after harvesting. The dried yellow flowers can be eaten after rehydrated. It is not only fresh and crispy, but also very nutritious. In addition, the roots and seedlings of yellow cauliflower can be used as medicine, and it is widely cultivated in our country, with a particularly strong adaptability, and the main cultivation areas are mainly in the north, with the four famous main production areas being Shaoyang in Hunan, Dali in Shaanxi, Suqian in Jiangsu, and Qingyang in Gansu. In the understanding of the yellow cauliflower planting area, the following we look at the yellow cauliflower in the planting process how to manage.

A, yellow cauliflower reproduction

Yellow cauliflower reproduction methods have seed reproduction, planting reproduction two methods.

1, seed propagation

To choose a good high-yield plants, in full bloom each stem to stay 5 to 6 buds flowering and fruiting, so that all the other buds are on time to pick, in the capsule ripe slightly cracked at the top of the time to pick off the detachment, sun dry and storage. Seeds are sown in the open field in September of the same year, and they can be sown in the way of strip sowing in a flat bed, and a furrow is opened at a distance of 30cm between rows, and the depth of the furrow is required to be about 3cm, and seeds are sown at intervals of 3~5cm. In the overwintering period, a small arch is used to prevent cold. In the spring of the second year, it is necessary to strengthen the management of fertilizer and water, and it grows into a big seedling in July, and then it can be transplanted in August, and then it can get a part of the yield in the third year when it draws shoots and bears buds.

2, split-plant reproduction

To choose the vigorous growth, more buds, long flower strips, good quality clusters as seedlings, in the buds can be carried out after harvesting. Be careful to choose a sunny day, digging and dividing seedlings, and then planting seedlings. Minimize root damage when digging and dividing the seedlings, as this will encourage the seedlings to grow vigorously and slow down quickly after planting. After digging up the seedlings, remove all the soil and separate them one by one, or you can separate them from a cluster of 2 to 3 tillers. At this time, it is possible to cultivate the plant by cutting off the old roots, diseased roots, and rotten roots on the plant and leaving only 1 or 2 layers of new roots with a root length of about 10 cm.

Second, make the field

The yellow cauliflower has to grow continuously for more than 10 years after planting, so it is necessary to make deep ploughing before planting, no matter it is a flat land or a sloping land, and to apply enough fertilizer, and if it is a sloping land, it is recommended to make it into terraced field, and it can be planted by using the ridge of the terraced field, which is based on the condition of the soil. For some areas with less precipitation it is recommended to use flat beds, which is convenient for water storage and irrigation.

Because the root system of cauliflower is more developed, and the tiller is fast, it requires looser soil, and deep plowing is used in plowing, and the depth of plowing is about 30cm, and the field surface should be leveled after deep plowing, and the upper and lower part of the field should be made solid.

Three, planting

After the buds are harvested, the best planting period is after the flower shoots are withered, because the yield of cauliflower depends on the density of planting, so it is necessary to determine a reasonable planting density and planting method before planting. Under normal circumstances, flat land, fat land, planting 1600 bushes per acre is appropriate, if it is sloping land, barren land, planting 1800 to 2000 bushes per acre is appropriate.

There are two ways of planting cauliflower: one is single hole planting, row spacing is 60~90㎝, hole spacing is 30~50㎝, and the method of double-piece planting or triangular planting is adopted; double-piece planting means that there are three clusters in each hole, and each hole has two buds, and the spacing between the two clusters is 12~19cm, and triangular planting means that there are three clusters in each hole, and each hole has 1~2 buds. Secondly, wide and narrow rows are planted in holes, and wide rows are 80-100 cm, narrow rows are 60-70 cm, and the distance between holes is 40-50 cm, and the number of buds planted in each hole is the same as that of single-hole planting. This kind of planting can fully utilize the advantages of the side rows, which is convenient for picking and management, and is suitable for large-area production.

Four, field management

1, soil cultivation

The reproductive period of yellow cauliflower is relatively long, and is easy to breed weeds, and at the same time in the picking period will often be trampled. Causes the soil to be compacted so must forest plowing and loosening 3 times a year. The first time is to be carried out after germination in the spring, and it is noted that this plowing can be carried out with fertilizer, and it is suitable to be shallower between plants and deeper between rows, and it is about 10-15 cm, and this plowing has the effect of turning over and burying fertilizers to loosen the soil and increase the temperature of the ground, and it can promote the early and vigorous growth of cauliflower, and the second time is to be carried out after cauliflower harvesting, and it mainly loosens the soil that has been trodden down to improve the physical and chemical properties of the soil, and the third time is to be carried out after harvesting. Physical and chemical properties of the soil, the third time is carried out after the cutting of leaves, this time it can eliminate weeds and reduce the damage of residual diseases as well as insect eggs.

Because the root system of yellow cauliflower grows gradually upward from the newborn basal nodes every year, and the shortened stems have the characteristic of growing upward and lifting up, then cultivating the soil can prevent the shortened stems and roots from being exposed and increase the number of flower moss. Generally planting 2 to 3 years after the start, in each year to do a good job of soil cultivation and root protection, especially soil erosion is serious slope is more need to pay attention to diligent soil cultivation. In the yellow cauliflower winter seedlings withered to spring seedlings before sprouting combined with plowing, fertilizer, soil cultivation, it is recommended that each mu of land soil manure is 4000 to 5000 kilograms.

2, fertilizer management

In the seedlings before the combination of ploughing for seedling fertilizer, should be applied into the fast-acting nitrogen fertilizer in order to promote the spring seedling of the thick and neat, in the shoots before the second fertilizer, which is known as the shoots of fertilizer and the fertilizer must be reapplied, per mu of land into the nitrogen fertilizer is 10 to 15 kg, potash 10 kg, calcium superphosphate is 25 kg. The calcium superphosphate is 25 kilograms. In the harvest season to carry out the third fertilizer, so that late more buds and reduce the phenomenon of falling buds to extend the picking period, this is called bud fertilizer. If it is in the barren land, then the effect of this fertilizer to increase the yield is very obvious.

3, bud measures

Yellow cauliflower buds are relatively easy to fall off, which will affect the increase in yield, the most fundamental measure is to strengthen the management of fertilizer and water, and timely application of caretaker buds to keep the fertilization, to timely irrigation drought and buds. After the yellow cauliflower buds, it is recommended to use 0.3% to 0.5% urea + 1% calcium superphosphate leachate + 0.2% to 0.3% potash, or 0.02% rare earth, combined with the spraying of 15 to 20 p.p.m./L of gibberellin, which is very beneficial to the strengthening of the seedling and the preservation of buds.

4, pest control

The pests of yellow cauliflower are mainly leaf spot disease, rust, and red spider, aphids and so on. After the previous year's harvest, we should pull out the shoots and cut the leaves in time to clear the garden. Because the leaf spot disease is usually in the middle of March, in the second half of May, the damage is more serious, it is recommended to use Tolbutrazine or Chlorothalonil for spraying prevention and control, rust is in the second half of April, the damage is more serious in June to July, you can use sodium dichlorvos or sulfuric acid to prevent and control. Red spider is mainly in the high temperature and dry season when the reproduction is very fast, you can use dicofol to prevent and control, aphids can be used aphid net to prevent and control.

Five, harvest

The harvest season of cauliflower is generally in June to August, the best time to pick is 13 to 14, the most appropriate period in the harvest is with buds with bracts, that is, the buds are full and still not open, the middle of the color of its golden, the two ends of the green, the top of the tip of the mouth is seemingly open not open, too early and too late are not good, if it is too early, it will not be too late. Will not be good, if it is too early, is the green bud, the sugar content is too little, so the quality and color will be too poor, the yield will be low, if it is too late, there will be? grin? open, so that is not conducive to processing, poor quality is not easy to preserve. Note that the picked buds should be steamed in time to prevent the grin from opening.

The above is the answer to the yellow cauliflower planting area and planting technology, such as you in the yellow cauliflower planting process, there are any questions, but also in the comments section, we *** with the discussion.
