How to plant heavy buildings with the seeds of heavy buildings

Selecting land for planting: select the land with shade and convenient irrigation. Sowing seedlings: generally sowing seedlings in January, select seeds with full particles and no disease, and then sprout in the sun for 3 days. Before sowing, carbendazim should be used to disinfect the soil. Scientific planting: the planting row spacing is about 30cm, and the plant spacing is about 20cm. Field management: reasonable watering according to the weather, pay attention to drainage. Pest control: Bordeaux solution can be used to control root rot.

First, select land for planting

The planting of heavy buildings is generally selected in the land with shade, shade and convenient drainage and irrigation. The heavy building is a kind of plant with shallow root system, the growth rate of the heavy building is relatively slow, the seedling raising time is long, so the request to the soil is relatively high. In the process of soil preparation, the stones and weeds in the field should be cleaned up, and the soil should be knocked fine and the ground level. In the soil preparation should be combined with fertilization, the base fertilizer planted in heavy buildings is generally rotten organic fertilizer.

2. Sowing and raising seedlings

Zhonglou is usually sown and nurtured in January every year. Seeds with full grains, no diseases and insect pests and no mildew are generally selected, and then the seeds are exposed in the sun for three days, mixed with river sand to promote germination, while keeping the river sand moist to ensure the full breathing of the seeds.

Before sowing, disinfect the soil with carbendazim, and then sow. When sowing, it is generally necessary to sow seeds in a trench with a row spacing of 30 cm-50 cm. Usually, seedlings emerge in about a week. During seedling emergence, the soil moisture should be maintained to promote seedling emergence and seedling growth.

III. Scientific planting

Generally speaking, the breeding time of heavy building is about one month, that is to say, the seedlings can be transplanted after a month, while some heavy buildings have to wait three years before digging up the seedlings for transplanting.

Transplanting is generally based on the spacing of 30 cm between rows and 20 cm between plants. after transplanting, if there is no shade in the planting ground, then it is necessary to build a shade shed in advance and pay attention to planting with soil when transplanting seedlings, so as to improve the survival rate of heavy building seedlings.

IV. Field management

The planting time of heavy buildings is usually in March and April, and there are more Rain Water in March and April, so there is no need for watering after transplanting, but at this time, attention should be paid to properly draining the seedlings of heavy buildings, so as to discharge excess water out of the field. If the weather is relatively dry, the seedlings need to be watered properly.

In general, heavy buildings are ploughed and weeded from September to October, and there is no need for deep ploughing to avoid damaging the roots of heavy buildings. The clock tower needs topdressing two or three times a year, mainly compound fertilizer, with a dosage of about 30 grams each time.

V. Prevention and control of diseases and insect pests

The main disease of the heavy building is root rot, which mainly harms the root system of the heavy building. the cause of the disease is that too much water in the field leads to root rot and plant death. If you encounter root rot, you can use Bordeaux solution to control it.
