How to grow olive vegetables in greenhouses, and what season is suitable for growing olive vegetable

Low-temperature resistant vegetables, at the beginning of the planting and seedling period, the required temperature will be higher, at this time the temperature in the greenhouse during the day should be between 26 degrees and 29 degrees, and not below 11 degrees at night, so that the roots of cabbage will grow faster.

Basically, after four days, it is necessary to slow down the seedlings and squat the seedlings, at this time the temperature should be slightly lower, the temperature is between 21 degrees and 26 degrees during the day, and the amount of water should also be controlled, so that the seedlings will be squatted for about 11 days.

It will pour the rosette stage, at this time it mainly depends on how the seedlings grow, and then when watering, 16 kg of urea should be properly chased, so that the leaves can grow faster.

When it comes to balling, you need more potassium fertilizer, phosphate fertilizer, and more water, to chase 21 kg of phosphorus and potassium fertilizer, you can keep the field moist, if the field is dry, you can do not need watering. During this period, the temperature should not exceed 29 degrees Celsius.

Season and time of olive vegetable planting.

Olive vegetables can be grown in summer and autumn, from late July to October, generally in July in the southern region, around August in the Disunlu district near the Yangtze River, and around October in the northern region. Olive vegetables sown in early autumn of 2010-2010 are harvested 30-35 days after sowing, and can be harvested 4-5 times later, with a yield of 2500-3000 catties per mu until the end of March of the following year. Olive vegetables sown in early October take 45-60 days to be harvested.

Olive vegetables sown in the spring are harvested in April, usually 1-2 times.

Olive vegetable harvest season.

1.Sowing: Choose fertile and loose, well-drained soil, pour an appropriate amount of water on the soil, then sprinkle healthy seeds on the soil layer, and then cover with a thin layer of high pat soil, water it fully to keep the soil moist; 2.

It takes about a week for the seeds to germinate. When the seedlings grow to 1-2 leaves, remove the diseased seedlings and keep the healthy plant spacing of 3-5 cm; 3.When the long is brought to 3-5 leaves, it is time to transplant and plant.

When transplanting, take care to avoid damaging the roots. The spacing between the plants is 10-15 cm. It can be watered thoroughly after planting.

<>1. The planting time of olives. Olive planting is carried out after Qingming (nutrient bag seedlings can be planted in other seasons except winter). The curvature of planting mistress should be determined according to soil conditions.

Generally, it is advisable to plant 20-30 plants per mu. Before planting, the hole should be opened and sufficient basal fertilizer should be applied. Strengthen the management of young trees after planting for 1-2 years, and master the principle of diligent and thin application in fertilization.

It is mainly based on fast-acting water and fertilizer. After 3-4 years of planting, the grafted seedlings can flower and bear fruit.

2. Reasonable dense planting. Olive is a light-loving plant, in its whole growth process needs to have sufficient light, but also in order to facilitate the later field operation, so when planting, it is necessary to plant according to a reasonable density, usually it is best to plant two meters apart in each row, each plant is about one meter apart, and an acre of land can be planted with an average of about 20 to 160 olive trees.

3. Water and fertilizer management. In olive cultivation, the fertilization period and amount are determined according to the age, vigor of the tree, the amount of fruit, and soil fertility. Generally, pre-flowering fertilizer is applied in March, and medium-fast-acting fertilizer is combined with farmhouse fertilizer.

From August to September, apply strong fruit fertilizer, partial fast-acting fertilizer and plant growth regulator top dressing. After fruit picking, farmer's organic fertilizer and other elemental fertilizers should be reapplied, and the soil should be turned over, applied deeply, and covered as much as possible. Rainy days should be drained and irrigated in time to ensure the normal growth of the tree, especially in each shoot pulling period and fruit expansion period to ensure that there is a proper water supply.

4. Shaping and pruning. The pruning time is summer and winter, and the pruning method adopts a combination of stub thinning and topping. Cut off the long branches, thin out the inner branches, overlapping branches and sick insect branches, and open the skylight at the top of the canopy to control the height of the canopy and ensure the fruiting of the outer canopy.

Before the summer shoots are ripe, the apical buds of the main stem and the apical buds of the main branches are cut into 6-10 cm to promote the growth of the lateral buds of the branches.

5. Pest control. Olive pests include psyllids, leaf-curling moths, and skin moths, while the disease is anthracnose, which occurs at high temperatures and is prone to leaf and fruit drop. If you can use biological control, winter pruning and manual hunting, you can control the occurrence of pests and diseases.

Olive seedlings or seedlings can be planted in the greenhouse, and the seedling height cannot be planted in the greenhouse after the height of the greenhouse.

1.The usual height of the greenhouse, the width of 10 15 meters, the length of 45 66 meters, covers an area of about 660 square meters, easy to manage and conducive to production.

2.Olive seedlings or seedlings can be planted in the greenhouse, because the height of the greenhouse is not high, suitable for planting relatively short seedlings, when the height of the greenhouse is almost exceeded, it can be moved out of the shed for planting.

3.Olive olive is an arbor plant of the family Oliveaceae. It can be up to 35 meters high and up to 150 cm in diameter at breast height.

Because the olive is a relatively tall tree species, it is not suitable to be planted in the greenhouse, and the height of the greenhouse is difficult to meet the requirements of the olive tree.

Olive vegetables can be grown in summer and autumn, from late July to October, in the southern region in July, a little later in the Yangtze River around August, and in the northern region around October. The olive vegetables sown in early autumn are harvested 30-35 days after sowing, and can be harvested in phases 4-5 times thereafter until late March of the following year, with a yield of 2,500-3,000 kg per mu.

Olive vegetable harvest season.

Olive vegetables sown in early autumn, harvested 30-35 days after sowing, can be harvested in stages 4-5 times, clump until late March of the following year, the yield per mu is 2500-3000 kg, the olive vegetables sown in early October need to be planted for 45-60 days to be harvested, the spring sowing of olive vegetables is harvested in April, generally harvested 1-2 times, and the yield per mu is about 1000 kg.

Olive vegetable planting steps and methods.

1. Sowing fierce seeds: choose fertile and loose soil with good drainage, pour an appropriate amount of water on the soil, then sprinkle healthy seeds on the soil layer, and then cover with a thin layer of soil, and maintain the moisture of the soil in full watering;

2. It takes about a week for the seeds to sprout, and when the seedlings grow 1-2 leaves, remove the sick and weak seedlings and keep the healthy plant spacing at 3-5 cm;

3. When 3-5 leaves grow, transplanting and planting are required, pay attention to avoid hurting the roots when transplanting, the spacing of the plants is 10-15 cm, and the water can be watered thoroughly after planting.
