Capsule s cabbage is generally wild, is there a variety suitable for artificial cultivation?

Shepherd's cabbage is not suitable for artificial cultivation, because there are many natural grows in the wild, and the cost of shepherd's cabbage is low, even if it is cultivated in a large area, it can't be sold, and it will lose money in the end.

Shepherd's cabbage has begun to be planted in many places, and shepherd's cabbage only has the purple root and white flowers, which is the most delicious, so most of them are planted with that variety, as long as the water and fertilizer keep up with the shepherd's cabbage, each tree grows big and fat.

At present, there are two main types of cultivated varieties of Capsule. planifolia and Capsule. flowerifolia. Camelina plate-leaved, also known as large-leaved camelina spp., thick leaf head, its leaves are large and thick, flower-leaved camelina is also called small-leaved camelina and broken leaf camelina and scattered camelina leaf.

There are two varieties of shepherd's cabbage, which can be divided into planifolia and loose-leaved shepherd's cabbage according to the leaves of shepherd's cabbage. It can be planted in spring, summer, and autumn. Planting is mainly carried out from late February to late April in spring, July to early August in summer, and September to early October in autumn.

1. Pursed cabbage: This kind of shepherd's cabbage, also known as large-leaved shepherd's cabbage, is a Shanghai variety, the leaf color is light green, relatively thick, the length is ten centimeters, the width is in centimeters, the leaves are relatively smooth, slightly fluffy, especially in low temperature weather, the leaf color will become darker. Camellia is not only cold-resistant but also heat-resistant, the growth cycle is relatively short, it can be harvested in almost 40 days, and the yield is relatively high, and the appreciation from the outside is very high, but the taste and aroma are not too strong.

2. Loose leaf shepherd's cabbage: This kind of vegetable has the reputation of small-leaved shepherd's cabbage, the plant is collapsed on the ground to grow, the leaves are greener than the large-leaved shepherd's cabbage, relatively narrow and short, there are about 20 leaves, the same low temperature will also become darker and purple, but it is not too cold-resistant, more heat-resistant, the fragrance is very strong, the taste is also delicious, especially suitable for planting in spring.

(1) Strictly select plots and level the furrow surface: It is advisable to choose plots with fertile soil, loose soil and strong water and fertilizer retention for the cultivation of shepherd's cabbage. Because the seedlings of shepherd's cabbage are small, weeds are easy to affect their growth, and the plot where shepherd's cabbage is planted also requires fewer weeds.

After the previous crop is vacated, part of the base fertilizer is applied and ploughed. The depth of ploughing is not strict, but the furrow surface should be leveled and fine, otherwise it will affect the emergence of shepherd's cabbage seedlings and the width of the furrow.

2) Timely sowing: spring cultivation of shepherd's cabbage, generally sown from late February to late April, and harvested from early April to late May. Shepherd's cabbage is generally sown with dry seeds.

That is, the dried seeds are mixed with some fine sandy soil and then evenly sprinkled on the furrow surface. After sowing, gently rub with a rake and step on the furrow again to mix the seeds with the soil. Kilograms of seed per mu.

3) Timely topdressing and watering: spring sowing of shepherd's cabbage can emerge after 7-15 days. After sowing and during the emergence period, care should be taken to keep the furrow surface moist.

If the weather is dry, water lightly often. When the seedlings have 2-3 true leaves, the seedlings can be properly thinned, suitable for the seedlings to be topdressed, watered, 10-15 days later, the second topdressing, and watering, each time the ammonium sulfate can be topdressed 10-15 kg, when the shepherd's cabbage is watered, the amount of watering should not be too large, in case the foliar silt caused by flooding with water. In case of waterlogging, it is necessary to drain water in time, and after the heat and rain, it is necessary to use well water to irrigate and cool down to prevent rotten roots and dead seedlings.

4) Pay attention to the prevention and control of pests and diseases: the diseases that harm the pursed cabbage mainly include downy mildew and virus diseases, and the insect pests mainly include aphids, diamondback moths, yellow striped jumps, etc. Downy mildew of shepherd's cabbage is prone to occur and spread under the conditions of high temperature, high humidity and poor drainage.

To prevent and control downy mildew, we should pay attention to field drainage and strengthen field management; In the early stage of the disease, 50% Fumei double wettable powder can be sprayed for prevention and control, and the prevention and control of viral diseases should be implemented. and to eradicate aphids to prevent aphids from spreading poison. When aphids are harmed, 40% dimethoate emulsion can be used to control 1000 times. When diamondback moth and yellow stripe jump are harmful, 90% crystal trichlorfon can be sprayed 1000 times, or 80% dichlorvos emulsion 1000 times spray for control.

The selection of camelina varieties is currently used to select from wild camelina in a directional manner, and there are two kinds of camelina macrophylla and small-leaved camelina respectively. Prepare the fields and plant them piece by piece. Choose fertile, loose, easily drainable, neutral or slightly acidic soils.

In fact, the requirements for soil are not strict, but the fertile and loose soil can make the shepherd's cabbage grow vigorously, the leaves are delicate, and the quality is good. Apply 1000-1500kg of fully rotted farmhouse fertilizer as base fertilizer every 667m2, rake finely and flat, make a furrow with a width of 2m, and rake the furrow surface flat and soft. Shepherd's sowing date:

Spring sowing in open fields from late February to early April, autumn sowing from late August to early October, spring sowing in protected areas from mid-February to late May, and autumn sowing from mid-August to late November. In order to adjust the market, the sowing period should be extended. When sowing, fine soil should be mixed, and sowing should be as uniform as possible.

After sowing, the furrow surface should be stepped on steadily with your feet, so that the seeds are closely integrated with the soil, and the soil moisture is maintained, so that the seeds can absorb water as soon as possible and emerge early. The seeds must be old from the previous year, as the new seeds of the current year have not yet left the dormant period. If possible, cover the furrow surface with straw, wheat straw, shade nets and other mulches after sowing to moisturize the surface of the furrow to facilitate the emergence of seedlings, and appropriate watering can be done in case of drought before emergence.

Management after the emergence of shepherd's cabbage After sowing, the seedlings can be fully grown in 5-10 days, and they should be watered once after the emergence of the seedlings in order to take root and sprout. When the seedlings grow to 3-5 leaves, apply 1500kg of lightly rotting manure every 667m2, and then harvest water and fertilizer every time. The main pests and diseases of shepherd's cabbage are downy mildew, mosaic virus disease and aphids.

75% chlorothalonil 600 times solution for downy mildew control; Use the key to prevent and treat viral diseases with 20% viral toxin A600-700 times; 10% aphid lice net 300 times liquid control aphids picking shepherd's cabbage when the seedlings grow to 10-13 leaves, they can be harvested in time, 500kg can be harvested per 667m2, and the total yield can reach 2500-3000kg. When harvesting, the big ones should be picked and the small ones should be left, the dense ones should be kept small, the strong ones should be kept the weak ones, and the harvesting tools should be picked well and dug with knives. Keeping Seeds for Cultivation of Shepherd's Cabbage Cultivation of Shepherd's Cabbage requires a separate field for cultivation.

The seed farm should choose the land with high terrain, good drainage and moderate fertility. Sow seeds in the seed field from late September to early October, with a seed amount of 1kg, and sow evenly. In mid-February, the plants were selected and selected, the weak and inferior plants and miscellaneous plants that did not meet the characteristics of the variety were removed, the plant spacing of 12 cm square was maintained and topdressed once, the sprouts were sprouted in late March, the flowers were flowered in late April, and the seeds were harvested in early May.

Timely harvesting is key, and the right harvest time is when the pods turn from green to yellow. Harvest before 10 a.m. on a sunny day, dry in the ground for a few hours, then spread it in the ground with film or straw mat, rub out the seeds, dry them, and avoid exposure to the sun. 50kg of seeds can be harvested per 667m2, and the seeds are orange and bright.
