When is the broccoli harvested? How to achieve high broccoli yields?

Under normal planting conditions, cauliflower growth needs suitable soil, water, light and temperature and other natural conditions, only in the case of reasonable conditions, can ensure high yield and high quality of cauliflower, among them, reasonable fertilization is the key, but other cultivation measures can not be less. Cauliflower has different nutrient requirements for different growth stages, before the emergence of flower buds, the amount of nutrient absorption is small, with the emergence and expansion of flower buds, the nutrient absorption increases rapidly, and the peak period of flower bulb expansion is the period when cauliflower absorbs the most nutrients and the fastest speed.

<> the amount of fertilizer should be increased, especially phosphorus and potassium fertilizer, to promote the growth of leaves and flower bulbs. 1-2 times before the amount of fertilizer, 5 kg of urea per mu each time, cauliflower topdressing must be combined with watering, especially the leaf ball formation period needs a lot of water. Cauliflower is a semi-hardy vegetable that prefers warm and humid climates and is neither tolerant to heat and dryness, nor tolerant to frost damage.

The appropriate temperature for seed germination is 20-25 degrees Celsius, the suitable temperature for seedling growth is 15-25 degrees, the suitable temperature for flower bulb formation is 14-18 degrees, and the flower bulb grows slowly below 8 degrees.

Cauliflower is a shallow-rooted plant, which likes moisture and is afraid of waterlogging, and requires loose soil and good fertilizer retention. Therefore, high-quality organic fertilizer is mostly used as base fertilizer in production. Such as well-rotted chicken manure, manure, biogas slurry, plant ash, etc., in addition to the application of basal fertilizer should also be applied an appropriate amount of available nitrogen, Hualai from the seedling stage to the harvest period have higher requirements for nitrogen nutrition, nitrogen fertilizer is sufficient, is conducive to the generation of strong seedlings, so as to form a strong leaf group and is conducive to the growth of flower bulbs in the later stage.

Nitrogen-deficient plants at the seedling stage are short, and are easy to cause early budding, and the flower bulbs are small, resulting in low yield.

To grow cauliflower to obtain high-yield, high-quality flower bulbs, there must be a strong leaf cluster to ensure it. It is required to meet its water and nutrient needs in a timely manner, so that the plants can grow vigorously in a timely manner, so that they can form a sufficient nutrient area in front of the current ball. In the early stage, more nitrogen fertilizer is consumed, the demand for nitrogen reaches the peak in the rosette stage, more phosphorus and potassium fertilizer is needed in the leaf ball formation stage, and there are special requirements for boron, molybdenum, magnesium and other nutrients.

The best time to harvest is in the spring, which is very good, and as long as you grow this broccoli well, it will definitely have a high yield, and it is very convenient and fast to raise.

Broccoli is harvested in the autumn months of October and November. If you want to achieve high yield, it is nothing more than to choose good seeds, ensure sufficient sunshine, apply fertilizer frequently, ensure sufficient moisture, and control insect pests in time, so that you can achieve high yield.

Generally speaking, broccoli should be harvested early in the morning and late in the evening. If you want to achieve a high yield of broccoli, you must pay attention to fertilization, watering and light to ensure the growth of broccoli.

It should be in the fall, around the time of October to November. And it should also be watered and fertilized in time, and at the same time, it should ensure sufficient sunlight.

The harvest time is 100 days later, if you plant it in the spring, then you can harvest it in the autumn, and it grows quite fast, and when it rains and blooms, you can add a lot of fertilizer to stabilize its nutrient structure, and you can achieve high yields.

For your reference: the exact planting time of bai needs to be based on the variety, local climate, and dao

as well as facilities planted with warm interiors.

shed, cold shed, protective capacity.

Ground, open air.

With a certain variety, for example:

Cool 3 July sown, 6 October harvested.

Generally 1 3 months sown and 4 June harvested. Or sow in 7 August and harvest in 10 November.

Warm land 1 Sowing in early March and harvesting in mid-April and early June. Or sowing in late July, late August, late October, and early December.

It is recommended that you choose the right time for planting according to the variety, local climate, and facilities.

It takes about 105-150 days for broccoli to be harvested from planting to harvesting. Broccoli seedlings are in the stage, from sowing to 5-6 true leaves, the seedling age is 30-40 days, the flower capacity ball will appear in the vegetative growth period, it takes 60-90 days, the period needs sufficient nutrients to promote the vigorous growth of leaf clusters, the flower bulb growth period takes 15-20 days from the appearance of flower bulbs to harvesting, after the flower bulbs appear in this period, flower buds and flower stems continue to develop and grow, reaching the commodity harvest standard.

The growth period of broccoli is about 90 to 110 days, broccoli is planted in September, and the broccoli will mature in October-November.

Maintenance method. 1. Substrate selection: broccoli will grow well in loose, breathable and well-drained acidic soil, and can be planted after mixing bean dregs, animal manure or humus with soil, or adding nitrogen fertilizer to increase soil fertility.

2. Water management: Growing broccoli requires keeping the soil moist but not waterlogged, and it is recommended to water it every 5 to 6 days. When it is dry and does not rain, increase the frequency of watering depending on the situation to keep the soil moist.

When the rain is heavy, drain the water frequently to prevent broccoli from getting sick.

3. Nutrient management: nitrogen fertilizer and potassium chloride at rosette stage.

Mixed application two to three times, the flower bulb expansion stage needs to apply phosphorus fertilizer and nitrogen fertilizer, foliar fertilizer can be sprayed with Bika foliar fertilizer and other trace elements.

While producing sufficient nutrients for the plant, it can also make the surface of the broccoli more green, more beautiful and beautiful. In summer, the sun is strong, so take good shade measures.

Now planting broccoli, under normal circumstances, it can be harvested in November, because broccoli is not planted for a long time, and it is relatively simple when he harvests, but it must be harvested when the weather is cool to be able to better keep.

Broccoli can be grown in two crops, generally planted in March and harvested in June each year. When growing broccoli, choose loose and fertile soil to ensure that the soil is breathable. Control the temperature between 20 and 30, properly shade and protect in summer, and ensure more than 6 hours of sunlight every day.

Fertilize the limbs once every half a month, and do a good job of adequate nutrient supplementation.

The temperature is suitable, and broccoli can generally be grown in two seasons, in March and July each year. Planting starts in mid-March and is generally harvested in early June. If you plant it in early July, you can harvest it in mid-September.

Broccoli prefers warm, moist conditions and is mostly planted in March.

Broccoli prefers loose and fertile soil to ensure the air permeability of the soil, and can add sediment and gravel to effectively promote the absorption of roots. In the rainy season, there is a lot of rain, so do a good job of soil drainage to avoid water accumulation and root rot. Ensuring that the soil is slightly acidic can promote the continuous growth of broccoli.

The suitable growth temperature of broccoli is between 20 and 30, and the temperature rises in summer, the light is strong, and proper shade protection is required, and water can be sprinkled in the air and on the surface of the leaves to cool down and moisturize. Ensuring more than 6 hours of light a day can effectively promote the continuous growth of broccoli.

The growth of broccoli is inseparable from sufficient nutrient supplementation, and during the growing season, organic fertilizer can be applied once every half a month. Fertilizer should be diluted before use, and if the concentration is too high, there will be root burning. Watering in time after fertilization to ensure that the soil is in a moist state can effectively promote the growth of broccoli.

<>1. The normal planting season of broccoli is in autumn, generally sowing in autumn, winter is the season of its growth, and it can generally be sold normally after the Spring Festival. The seeds begin to bloom in the spring and mature around April and May, but now they can be planted and marketed at the desired season using some techniques such as greenhouses. The best planting season is in September and October, when the phenology is the most suitable and the value of the grown vegetables is the highest.

2. Land preparation planting, broccoli planting needs to be cultivated and weeded, and fertilization is required in the early stage of growth. First of all, it is necessary to water enough water before planting to ensure that the soil is moist, and then spray the appropriate amount of pesticides, which need to be evenly and comprehensively sprayed on the furrow surface, in order to inhibit the growth of weeds, do not move the soil when planting, and it is not suitable for cultivation after sealing. In order to promote the nutrient absorption of broccoli roots, we need to cultivate it in time to improve the permeability of the soil.

3. Reasonable watering, broccoli is suitable for planting in a moist soil environment, and it needs a lot of water when growing. Generally, the soil moisture content is controlled at about 75, and excessive water content can easily lead to the incidence of pests and diseases, such as flower ball rot. After the flower bud differentiation and entering the flower bulb formation stage, the water demand is the period with the greatest amount of water, and if the required water cannot be provided in time, it will affect the formation of the flower bulb, thus affecting the yield and quality.

It is also necessary to maintain sufficient moisture during harvesting, otherwise it will also affect its economic value, and there will be looseness, deformity, etc.

4. Reasonable fertilization, broccoli needs a lot of nutrients in the growth process, and the larger the plant, the larger the flower bulb. First of all, we need to ensure the normal growth of the plant, and carry out top dressing in time to promote its growth and luxuriation, so as to ensure the expansion of the flower bulbs. Broccoli has a very large demand for nutrients in the early growth stage and budding stage, so we mainly use nitrogen fertilizer and apply it with an appropriate amount of phosphorus and potassium fertilizer.

In the peak growth period of broccoli, it is necessary not only to apply more nitrogen fertilizer, but also to supplement some trace elements and spray an appropriate amount of foliar coarse and rapid burial fertilizer to ensure that its nutrition is comprehensive, which can improve the yield of broccoli.

5. Field management, it is necessary to strengthen field management, do a good job in the prevention and control of pests and diseases in advance, and reduce the incidence rate. If broccoli is found to be diseased, it needs to be treated in time, such as downy mildew, which can easily cause black mold if not treated in time, and aphids carry viral diseases, which will affect the growth of broccoli. Therefore, we should conduct regular inspections, find and deal with pests and diseases in a timely manner, do a good job in prevention and control in advance, and improve the quality and yield of broccoli.

1. Sowing time. Broccoli is usually sown in spring and summer, in March and July, when the climate is mild, which is more conducive to the germination and growth of broccoli.

2. Planting method. The planting method of broccoli is very simple, generally sowing seeds by spreading the seeds evenly on the soil, then covering with a thin layer of soil, and gently compacting. Then water enough to keep the soil slightly moist and avoid water accumulation.

3. Growth temperature. Broccoli likes a warm environment, the best growing temperature needs to be kept between 5-20, if the temperature is more than 35, then you need to shade, otherwise it will also sunburn the broccoli.

4. Fertilization management. Broccoli is inseparable from nutrients, and regular fertilization is required during the maintenance period to promote the growth of the plant. Broccoli grows quickly, so there is a higher demand for fertilizer.

The best time to grow broccoli is in the fall, and spring planting is also acceptable. In fact, broccoli can be planted in two seasons, from March to July, planted in March, and eaten in June, if planted in July, then it can be eaten in September, and the broccoli planted in March will be more than the broccoli planted in July.

Soak the seeds in warm water for 3-4 hours, then sow them in breathable soil, and apply fertilizer once after 1 week after the emergence of seedlings (direct sunlight should be controlled for about 6 hours during the growth period), and the second time can wait until the flower bulbs grow before applying them, and then maintain the moisture of the flower bulbs.

Open air planting can be done around April every year, and greenhouse planting can be planted around October every autumn, but there are obvious differences in the climate between the north and the south, and the planting time will be slightly different in different regions.

Broccoli can generally be grown in two seasons, in March and July. Planting starts in mid-March and can generally be harvested in early June; If you plant it in early July, you can harvest it in mid-September. Since broccoli prefers warmer to cooler weather, the harvest in March is generally better than the harvest in July.

Broccoli does not have high soil requirements, prefers sandy soil, because it prefers more breathable soil, sandy soil will increase the yield of broccoli to a certain extent. The soil needs to be composted in advance, and weeds cannot be left in the soil after being cleared. The location of the land should be high, the drainage should be convenient, and the soil should be kept in a semi-wet state, which can strengthen the soil permeability, and the soil can be slightly acidic.
